Great video. Can do a video talking about the differences between Silver face and Black Face Fender combo's. Particular a 1976 Fender Twin Silverface. I found one cheap like 1k used in mint condition.

This is my amp and I have to say that I am really happy with the job that Brad did. Sounds incredible when Brad plays it and pretty darn good when I do. It now sounds like my old BF DR did back in the early '70s. Before I had this one serviced, it sounded good on low volume but when it was turned up, I could tell that something was wrong, aside from the reverb crackling and the non-existent tremolo. I bought this last November at GC for $800. They had it priced like a reissue and that's what I think they thought it was. I knew it could not be a RI because it didn't have the drip edge, unless somebody had taken them off. When I saw the 120V receptacle in the back I knew it was an antique. I snapped it up. Even a blind dog finds a bone once in a while. I wish I'd fixed it sooner. Thanks again Brad for the fine job you did. Not to mention the thrill I got watching my amp being worked on. Great video! Do I get any residuals???

I bought one several years ago, It was not in as good condition, no label speaker, vibrato disconnected. We used the intensity pot for a mid/gain boost, put 6L6GC tubes, and a Vintage 30, really smoked. I traded it for a Mesa MK I reissue head. Live the Mesa, but miss the Fender.

Pat Crowe - hey this is my stolen amp! I demand residuals from all these residuals. Actually I can't prove any of that. Have a nice day.

I have a 1979 Deluxe. Bought it used for $200 when I was in high school. Played in a band in high school and college and grad school. Still play sometimes with the same guys. We lost 2 band members, one to cancer, and the other to cardiac arrest. This amp was a godsend and it still sounds like gold. Sweet as honey and smooth as butter. Great video.....

The model numbers starting in the Blackface era is date based. AB868 is August 1968, AA1270 is December 1970, AA1172 is November 72. So the 1172 version is the later one.The only difference between AA1270 and AA1172 is the placement of the standby switch. In 1972 they moved the switch in front of the filter caps prior to then it was placed after.

And AB763 is the killer one from the mid sixties. Amazing design.

Back in the olden days when I was getting my start, I always got stuck with Fender amps. I hated them. I wanted a Marshall, damn it! I sold my last Deluxe back in the mid-nineties. I've regretted it ever since. I've pined for one ever since. I would truly - at long last - appreciate what they do so well.

used they are going for 1500 to 1800 on Reverb.

About 15 years ago I received a 1967 Blackface Deluxe (non-reverb) from my father, who purchased it back in ~1973! It is a beautiful amp, and sounds absolutely incredible! Perfect size for a guitarist as well - it gets quite loud by itself, and if you need more you can PA it easily. The Deluxe is easily one of the greatest amps ever made!

I remember the goosebumps that ran down the back of my neck when I first played a Telecaster into one of these. Excellent, as usual.

Way back in the seventies, not only did we think those CBS guitars were crap (and were driving the prices of real Fenders up), but those silverface amps had lots of problems; they were generally very noisy and crackly; I'd be happy, though, to own that amp. I've had a couple of Deluxe Reverbs over the years, and can't say anything bad about them. I sold them when I moved here, due to the voltage differences. I found a nice 65 AC-15 here, and I'm trying to buy a friend's 63 AC-15. Both have the gold bulldog speakers that all the 60s Vox amps I've seen have.

Here in Adelaide South Australia where we speak correct English I feel compelled to correct the way you pronounce the word tremolo. It is Trem- Ah-Low. A good example is the intro on Ian Hunter's : Once Bitten Twice Shy, when he says Hello. Thanks you and good night.

Great to see some basics, like recapping the power stage. Helps beginners to see how it's done. And definitely great to see the home made optocoupler. It compliments the vintage look.

Just wanted to let you know the quality of your video in the close ups and chassis scans has been excellent. I'm doing my first scratch build of an AB763 and some of my technique questions were answered in your close ups. Thanks for stressing that as an important part of what you are doing.

46:56 This is the part which makes the video all worth it. The tremolo works!!! The way ya dealt with the resistor which influences the tremolo is really an art.

This and a 65 Princeton are my all time faves....had a 65 Princeton back in the day....paid $350 for it!....sold it fpr a nice profit....miss it dearly

Roy from IT Crowd "are you from the past?",I love that show and really enjoy your videos Brad. Thanks

This video couldn’t have come at a better time for me! I have a slightly older (but very similar) silver-face deluxe reverb that needs some TLC, and I was just thinking about doing this sort of overhaul this past weekend. Your detailed explanations really helped make me much more confident about exactly what I’d need to do. Thank you!

I owned a Blackface ‘67 at the same time as my ‘73 Silverface DR. I kept the ‘73 because it was a stronger-sounding amp. And I like the “saggy” 5u4, as well as F.R.E.D. rectifier circuits. Here’s the mods I’ve kept after tweaking it over a couple of decades: 1) the tone stack: changed to a pair of 0.022, with a 56k slope resistor. 2) that pair of 220k feeding the power tubes were changed to a pair of 100k. 3) a 0.1 cap was put across the opto-cell legs to eliminate ticking. 4) changed the 3 tremolo caps to all 0.02 to slow the tremolo. These are the mods that I kept that I learned about from Rob Robinette(dot)com.

Hey, that was fun to watch! Great video! Beautiful sounding amp! Nice work Brad!

All freaking hail the Great Guitologist! When he can’t get it to work he makes his own parts, now that was way cool. I just watched a Blackface version of that amp by Granville Guitars and that dude sounds just like you. He talks about what he should do but it isn’t part of the deal. This was great Brad, super informative, thank you!

So much passion and dedication in this video. I am not a technician but it was fun to watch. Hope the owner is still using this beauty.

I had a Fender Quad Reverb back in the 70's, when I first started on the guitar. Loved that amp. With a Stratocaster Deluxe, with the humbucker pickups.

I bought a ‘65 FDRR at a guitar show in January. Really happy with the purchase. As such, I enjoyed seeing the repair video and learning more about this model amp.

Thank you, thank you, thank you! What a great amp and what a tenacious approach you take. About 18 years ago I almost got my hands on a Silverface Twin Reverb , but it got scooped up before I could put a deposit on it at my local guitar shop, Jimi's Music Store on Sherbrooke Street West in Montreal QC Canada. I settled for a Traynor YGM-4 Studio Mate with tremolo & reverb which has a similar sound. After witnessing this video I don't think I'll look at a roach the same way again either, keep up the awesome work Brad. Thx Alfa

Hey, Brad - really enjoyed the video! As the owner of a Deluxe Reverb Reissue, I was really interested in the service and repair. Like you said, they are really great amps - use mine for jazz and blues - it packs a lot of sound in a compact package. Thanks, man!

man this video blew my mind!!! what a brilliant fella! i just bought a ltd edition 65 deluxe reverb (in western wheat form) its very nice aesthetically and sonically!!! great amp... was a toss up between the 65 and the 68 but when i saw the 65 all gussied up i couldnt resist !

My silly comment just below... Bottom line, this whole series of smallish reverb amps from the mid ‘60s were incredible. The first few years of silver-face had very little changed from the preceding blackface, and if any difference was done, are easily brought to black-face era specs. These are really fine amps. My Vibrolux Reverb still has the killer 2 prong cord, but a 3 prong cord is ready to put in next time I open it up. Its still dead stock, except for improved wire and RCA plugs on the footswitch. Your suggestion of changing the screen grid resistors, yes! Good idea, and endorsed by me. On amps that I have designed, I did not use those grid caps..They can be dropped to a few hundred pF and get a bit more sparkle. Just an idea for all of you.. When I do go to 3 prong plug, and remove the death cap and switch, I will be replacing the switch with a fixed resistor and a series pot that is wired in to the feedback circuit, to give me variable feedback..

Loved the opto coupler fix .Great stuff !

I"m not an amp tech, but I learned to do a cap job and biasing etc. I did two mods to my '73, which is basically identical to that one. I put a negative feedback loop disconnect switch on the back, and then also a pot controlled vibrato disconnect switch. With the flick of one or two of the switches, the amp becomes a really great blues machine. I took it to blues jams for many years and almost everyone played through it and loved it with the 2 switches adding 2 clicks of gain. Both are super easy to do....Thanks for the video.

The real rock stars are people like Brad. We would have no Hendrix etc. without. Thanks Brad!

That's a bit of a stretch, but nice of you to say.

My '66 blackface Bassman head got the Dan Torres mod I did myself ( back to '59 circuit configuration ), and my '66 blackface Deluxe (no reverb) got one channel and the driver caps replaced with polyester(shiny brown caps) which I also did myself. Both of these sound WAY better than they were when stock. Polyester caps made these amps, AND my early '70's Marshall Superleads sound WAY better than they originally did when purchased in the '90's. The Fender's have the cleanest tone hands down. They amplify EVERY thing....even my breath, if I were to breathe on the guitar strings! ( just kidding, but not far from the truth!). And the '71-'74 Marshall Superleads, after some modding, are now rock amp holy grails. All from info found within Dan Torres's book "Inside Tube Amps...The Book on Tube Amps Technology". Oh, I found a "PARTRIDGE" output transformer in one of my dad's old heathkit tube radios for a pair of 6L6's!! I duly took it out, and is now my '66 Bassman's output transformer! It sounds fantastic! But, the original OT sounded great too....but there was definitely a tonal difference. And yes, the bassman and superleads sound very close...since they both have the same circuit...as does the Deluxe!!!! Only difference is the Deluxe has 6V6 tubes (and output transformer and lower B+ voltage), instead of EL34,6550,6L6's, etc! Appreciate your video's!

Great information. LOVE the DIY for the Trem. Batman would be proud!! Love your PRS..

Incredible work there sir! The photo-coupler/photo-resister was the most interesting thing to see... What the "light" actually looks like inside... And how you made another one from scratch with new components. Pretty neat!

As its 5000 miles between you and my fender 30 i guess i have to be grateful to my local amp tech here in yorkshire, but he is just as thorough and proficient,that said, the deluxe reverb sounds like heaven with the trem sorted, a pleasure to see another great job .

Bought one used 1977 for $75 with a blown speaker, replaced the speaker and that thing sounded nice, later I traded it for a Yamaha 250 of which I regret now. Bought a Baseman in 1983 at an Imperial Beach California swap meet for $35 still have it, so far never had to change anything except tubes, I’m not a purest, just never had to replace the caps etc. I reformed the caps a couple of times (they probably didn’t need reforming the second time, just being careful) using a properly grounded circuit that puts a light in series with the amp with tubes removed and the hot side feeding the light to keep it as safe as I can. started with a 7 watt nightlight and worked up to a 75 watt light; all incandescent. After rebuilding a Silvertone 1482 I made the reforming circuit permanent.

Excellent as always, clearly spoken and executed. Thanks for your great work.

The Bat Man segway music? Oh hell yes! Now THATS the coolest shit in town. : ) I'm back.! This is probably one of the coolest videos you ever did. No FBI. No politics. No drama. No bullshit.

In my humble opinion, these are the most articulate amplifiers Fender ever made, regardless of era.

Brad, Enjoyed your video, and how you surmounted the hiccups of this amp! Proves the old admonition "If at first you don't succeed, keep on sucking till you do"!!

Great video, love the detailed explanations. And makes me appreciate my more recently acquired Blackface DRRI much more.

Absolutely fascinating! 'Love your commentary. Am I supposed to be so riveted by this process??? I'm an artist/musician but the mystery of electrical stuff was always of interest for me. Enjoyed it! Thanx.

Love my Silver face Deluxe (76). It is my go-to for any gig. I removed the bright cap in the vibrato channel and it is the best pedal platform ever IMHO

That was awesome to watch you bring that beauty back to life. Your playing is really good!! Nice job

Another highly instructive vid... I wuz really feeling for you as you doped out this repair. Thanx and... cheers

The Fender Deluxe Reverb is, in my own humble opinion, one of the best guitar amplifier ever built, blackface or silverface. It's a 20 watts amp powered by a pair of 6V6 output tubes which have the most beautiful tone of all the output tubes. The tube rectifier also contributes to it's amazing tone. But the 12" inch speaker makes this amp sound bold, big and awesome. Get your hands on a vintage Deluxe Reverb and you'll never look back!

I love those Batman esque zooms !!!!!!!!!!!!

nice job my friend. enjoyed that one very much. i was thinking of buying one of these and your comments gave me the confidence that this must be one of the best amps (for me). but cheap no they are not...people here in europe knows what is good ...lol....take care cheers

Nice work, nice amp, and nice playing!

This exploratory autopsy of this Deluxe was very enjoyable. The deductive elimination of suspects led to a wonderful case being solved. That deluxe has a sweetness, but maintains its punch throughout the test playing. Thank you sharing! One thing though, Brad...it is a tiny nit pick. You said the condition of this Silver Face was "clean as a whistle." I just wanted to point out that a whistle is full of spit. Enjoy your weekend!

Thanks for the pictures and the sound, great !!!🤩

Thanks for the vid! Working my way through a Super Reverb termelo / reverb problem. I got the trem working but the reverb was dead, then I got the reverb working and now the trem is dead. Appreciate the deeper look into the circuit.

Hey Brad - I find your videos to be absolutely fascinating and entertaining as all get out. I wish I had an amp I could say was repaired by “ Brad the Guitologist” ! Also, every time I watch one of your vids, it makes me wish I had gotten into this field when I was younger. Just absolutely entertaining and fascinating as I already stated. Kind of like the TV show “ How it’s made”, only better!

Wow, nice and thorough job, forgetting the vibrato needed to be shorted reminded me of me.

Used to own a twin reverb. 2x10s or 12s, I forget. Sounds better by a factor of 2. Gave up playing. Sold it for a song. I'm still crying about that. Best amp I ever owned. I'm playing again. Bought a Chorus with reverb, essentially the same thing.

Interesting and clear educational professionally made video as well as good repair and maintenance job! Thanks Brad.

Really enjoyed this “look inside...”. I’ve been playing through black and silver face Fenders since the 60’s, but always have had them serviced and repaired by my long time tech/buddy David Allen. In all that time, never seen the opto bulb revealed. Yeah, this was fun. Nice pickin’ too👍

Oh - forgot to add... just thinking... since the circuits are real similar, maybe BF vs SF differences could be due to quality/supplier of parts.

Great job - the amp sounds wonderful!

I have a '77 with a low midrange pot and a Fender twin speaker. Changed the OT to a blackface version. This amp sounds WONDERFUL ... I just don't hardly get to play through it ...

The snubber caps on the grids of the 6V6s are not on the AB763 or AA763 (Blackface) amps. CBS put them there to avoid intermittent oscillations caused by sloppy wiring when they took over the company. On the smaller amps like the Deluxe Reverb they did not change much on the amps but on the larger ones they did. This is one of the few changes they made. Some people refer to those caps as "tone suckers". I own a 1969 model and that is the only difference between it and the '64s and '65s that I have worked on. I lifted one leg of those caps and put heat shrink on the leg I lifted in order to "blackface" my amp. I can put it back to original easily and mine was wired good enough that it didn't oscillate when I did the mod. Thanks for your video.

Loved this video. I have a DRRI from the 90s (back when they were still made in the States) and she's tonal nirvana. I did get the evil bright cap mod'd with a push/pull bypass knob and a better cap.

Why don't you have any albums out?You are clearly an amazing guitarist!Just you jamming at the end of these vids makes me want to buy them!Damn,even the sound quality and tone is amazing!

Hey Brad......there used to be an amp tech in Austin TX that sold the Surf Bug. It was a Trem-Mow-Low :) bug of his own manufacture that was supposed to be an improvement over the original bug. Went down and bought one from him and installed in my ProReverb. Big improvement, not Bias vary quality, bur much better than stock. Read an interview with him one time and he said the surf bug came about with him experimenting using LEDs for the light source, Took some trial and error until he came up with an LED that sounded good. Dont recall the guys name....he was a real cool guy only met him once and he talked to me like he knew me all my life. Unfortunately the business is closed as he passed away several years ago.

Nice work, Brad. While I admire your dedication to fixing the roach, they can be purchased already assembled for ~$10 and cost far less time to replace from places like TubeDepot and Antique Electronic Supply. Nice work and one additional suggestion. I use denatured alcohol to clean up the flux residue like what you had when you replaced the caps in the tremelo circuit. Cleans boards up nicely and safeguards you against future problems the flux can cause. Nice work and enjoy your videos!

If I already have the parts, making them myself is a no-brainer. Takes about 5 minutes. The hot glue was just me trying something different.

You can use smaller heat shrink to hold the trem roach together. Also while heath shrink is still hot you can pinch the ends closed. Good work.

This amp has had a lot of love .

Hey Brad, whenever I de-solder a wire or a component from a solder-terminal, I find that using some Solderwick de-soldering braid helps a lot, I use it to soak-up the majority of the solder and then it's just a case of using a pair of fine needle-nose pliers to un-wrap the component lead from the solder terminal, Solderwick de-soldering braid is a chemically treated copper braid that soaks up solder like a sponge soaks up water, very handy to have, I usually buy a couple of rolls of 3mm wide de-soldering braid from my local Jaycar Electronics store, Goot brand tends to be the best.

Great vid, I learned a huge amount from it. Thanks!

Great vid.I learned heaps about trem.Cheers

awesome video- thanks Brad

Its genius from where i sit, tp have the experience of knowing what is going to sound this good in comparison to the original components sympathetic replacements done, and then play some suitable and reverent noodling to project the end result beautifully , trem mend ous!

I go with my 61 6G9A Tremolux with 1x12 Tone Ring cab as my all time favorite Fender amp though it is difficult to argue that Deluxe Reverb isn't one of the all time greatest guitar amplifiers. This amp is heard on literally millions of songs. Basically anything James Burton played post 64 was done with a Deluxe Reverb. That would be into the 1000's of songs considering his breadth of studio work. Wouldn't think about selling mine any time soon as the Deluxe Reverb works for just about any genre of music except metal(okay with a pedal you can fake it). If this was my amp, I would have put a pair of Sylvania 6V6GT & a Mullard GZ34, but that is a cost money thing to do. Cool vid.

Good work and a killer sounding amp now. Thanks Brad.

The 1200pF caps do make a low pass filter with the 1500Ω grid stoppers, but they do not affect audio frequencies so do not stifle the sound in any way. That filter kicks in at over 80kHz just to prevent high frequency parasitic oscillations.

I had no idea the 22k dropping r could be substituted with something like a 2.7 . I learn so frigging much from your videos. Love that you.dont find it nessasary to always go with sprauge or f&t for filter caps. I built a ao29 trainwreck with the least expensive c and r that i had. Sounds amazing, and it's so damn much cheaper in the long run.
