My dad had a similar affinity and the abilities of PA. The skills he taught me and the smell of melting solder are greatly missed. Every time I plug in a guitar I remember.

I am a new viewer of your channel and feel like I have found a gold mine of information on everything about guitar amps. You talk about these amps in somewhat technical terms but guys like me who don’t work on their gear can still understand what you are talking about. I appreciate your honesty and objectivity and really appreciate what you are doing. I look forward to watching all of your old content and everything new. Great work and thank you from this Fender tube amp fan!

I hope the customer goes for the full boat with De-spaghetti-ing service. That will make for a great video series.

Excellent video. I love your clarity and the constant bits of knowledge and experience you share. So good. These old BF and SF Fenders are so wonderful. Thanks for this.

Just discovered your channel, really appreciate the quality of your work and videos. I recently picked up an original AB763 Super Reverb for $900 from a local pawn shop - hoping this video can help me evaluate it further!

I have one of these I bought 20 years ago. Really finding this vid helpful. Thanks as always

I own a '76 Super Six that came with 6 10" orange JBLs made for Fender. I had never seen these speakers before but I really like them.

I like the way the mid to late 70’s Super’s sound. They don’t do the chewy overdrive that the AB763 amps do. If you’re going for SRV style sounds, these do it bone stock.

Man I love those "ultralinear" Fenders. Such a fat plumb sound and lovely tight bottom end and have a nice breakup with the master volume.

The voiceover is amazing i love listening somehow it doesn't get boring...consider me subbed!

Such a great channel you have here!

Tempting amp to look into getting. That conductive board thing sounds expensive though. Thanks for sharing your knowledge Lyle.

Another informative video that helps. Thanks again for the time and care you put into this...the other instrument to go with your guitar 😎👍 REALLY looking forward to the video of amps @ $1k or >...😉

How could any dignified tube amp lover PASS UP this video.... with it's heading declaring the evaluation and inside look at a mid 70's Super Reverb!!!! Love all your work...and IT LOVES YOU!!! Excellent source of professional info and repair, on the top tube amps from the golden age. Gear cherished by guitarists! 👍👍👍

Just found your channel, been bingeing your videos. Very enjoyable watch, like Ted from twoodfrd but for amps.

Pleasure listening to you and watching the guts of amps :)

I picked up a '75 Super Reverb for $125. at a Ralph Lauren sample sale. Put $700. into it for a complete overhaul by a great local amp tech, including new Eminenece speakers. Best amp I've ever played. Great videos as always Psionic.

A 70's super is definitely one of the main vintage amps I'm interested in picking up at some point before the prices start rising.

Just wanted to say that you're content is top-notch, and I don't even own a tube amp. I'm an apartment dweller so modeling works great for me, though I do enjoy the analog design and engineering of tube amps. In any case, I really enjoy watching your content because it's well recorded, you know what you're talking about, and I learn plenty of new things every single episode.

Thanks Brandon!

I love Super Reverbs - it was such a treat to get a peek at what make these things tick. I've owned a bunch of Fender amps including Deluxes, Twins, Princetons and even an old blackface Champ, but there is just something special about the Supers (IMHO!). Really fun and informative video to watch! Many thanks!

Such great knowledge, thank you!

Interesting thing with thoes late 70's super reverbs, they have the same chassis size as the twin reverbs and the supers also got the addition of a mid pot on the normal channel. They standardized the chassis for all the big boy amps during that era and the good news is, you can find various cabinets that will fit the chassis with different speaker configurations.

Didn't want to brag but I got mine for 600 bucks.

These are fabulous pedal amps. Cut the wires to the volume boost feature and replace the reverb driver's 620 or 680 ohm cathode resistor with a 2K2 resistor and a 22uF or 25uF shunt cap. The 90% treble bleed master volume pot was a nicely executed master volume idea. I use a Fein multitool to cut the baffles out. Easy peasy, and it goes quite fast too. I use a drywall knife. It is just super wide putty knife I use to separate the chassis. I also use it for drywall mud, wood pore and body filler.

That is a fantastic amp. Wow! I would love one of those. I have a 78 Twin Reverb and it's amazing!

Fabulous video, thank you for sharing your expertise, so much great information and demonstrations. Please take good care of your wrist. (:

I did a recap on a 1969 Deluxe reverb last year. The doghouse was also stuck, but because one of the original caps bursted open and the electrolyte was gooped and holding it on. Gnarly project.

I did actually get an old silver face SR for less than the reissue just a few days ago. Bone stock. Fingers crossed! 14 day return policy. I suspect this video will be very helpful in the future :)

just got a 77 super like this one, £1000, totally original condition apart from 2 changed speakers, (eminence) cool old Zaerix 6L6s, sounds phenomenal! just needs a recap as it still has the original Mallory caps, will probably add some castors too, best amp i’ve ever played.

Our guitar tech has one of these SF DR's that he tuned up. A client never picked it up 20 plus years ago. Just a killer tone machine. He has sold more guitars due to how good this amp sounds. I recently acquired a 78 DR that just drips tone. Just slays my buddy's 3k Allesandro DR - RI.

Interesting video! The Lindal tubes look like rebranded GE 6L6GC's. I have an old Plush Super 450 twin with original GE tubes that look like those.

Your playing is fine.

Terrific! Thx.

IMO, any silverface is worth the rehab, provided it's properly done.

This one is an ultralinear model, if I'm not mistaken. Very different beasts from the MV Fender amps from the mid-'70s.

Three years ago (back into guitar for a year and a half after a 30+ yr break) my local Sam Ash had a clean looking 69 Super reverb ($900) that sat in the store beckoning to me for 8 months to a year. If I'd only known what I know now...

Those early silverface amps are the shit. My first "cranked tube amp" experience was a 1970 bassman head through a 4x12

that really is a gem of an amp considering its age ...I have an old '76 Deluxe Reverb that looks like a rat was living in it! CBS era amps really were terrible with the lead dress! ...So I Blackfaced the Power section, and replaced all the Electrolytic Caps(Power supply, Bias and bypass). The amp sounds fantastic, and is dead quiet! I wouldn't dare try to clean up anything inside fearing that I lose some of that mojo!

BB KING'S FAVORITE AMP! That concert gig album he did a prison,that's what he drove the shit out of with his Lusile, beautiful singing tone, I had to get one or two.

I have had one of these since the early 80's. VERY misunderstood amp. Fender should have given it another name. I think alot of players expected them to sound like a pre-CBS Super and they have nothing in common. ALSO...Boogie was coming on and the master volume is not gonna give you that kind of drive. More like a Twin than an older Super. I love mine...clean straight to the top with just a bit of break. I use other amps for overdrive sounds. These do behave well with pedals though. Great breakdown!

I think Lindal was a brand for RCA tubes manufactured in Japan. I have a NOS pair of their 6L6GCs stashed somewhere, and they look and measure like RCAs.

Omg I totally played a 78 Super Reverb at a local guitar shop a few days ago! It was cool but fuckin HEAVY!!!

Your videos are great. Do you take on any out of state work, ever have customers mail you chassis’ to work on? Thank you

that 'dough cutter' tool is properly called a scotch; really good video, many thanks any cahnce of doing a similar series for bass amps/combos please ?

You could rebrand that dough cutter now and sell them on stewmac for fifty bucks… specialist tolex spreader 😂

Great video! I have a basic understanding of capacitors, resistors, impedence, etc. I've also watched videos on how tubes work but what this video taught me is that I really need to take my vintage amps to a qualified tech to get inspected. The one vintage amp expert in Kansas City, Don Warner, unfortunately had to retire due to health issues before he could get to my amps. I was fortunate to pick up an all original, to the best of my knowledge, 1976 Super Reverb from GC. Still has the RCA blackplate tubes and those sweet alnico speakers. I absolutely love it and have been playing it for several years with no issues but now I'm worried that the caps may be a ticking time bomb. I bought a 2nd '76 SR that's in decent shape but has had the master volume disconnected. I also have a 1968 Bassman that needs serviced. Any recommendations for a qualified tech in the KC area? I also travel back to Ohio, Columbus & Akron/Canton area, frequently if any qualified techs in those areas as well.

I have a late 70's twin reverb. It has a grounded 3 prong electric cord. Do i have to worry about this death cap or getting shocked. I have been playing guitar for 30 years and never heard of this until i watched your videos. What should I do. I have owned this amp since the mid 80's and it was never abused. It was serviced a couple of times but no one ever mentioned this DEATH Cap thanks Great videos Learning a lot

I had a super twin that really didnt like being upright it had a eq channel and a horrible lead channel. I used it for years till it fell at a guys house and punched in the power switch. I wasnt that hirt because everytime id move it my elbow would hurt for 30 min or so.

Another reason for replacing the entire power cord: Typically with these cords from this era, the rubber insulation on the inner conductors reacts with the copper strands, turning them black. In this deteriorated state they are hard to solder and I’m guessing have reduced current carrying capacity. Those old cords have got to go!

@OpSic66

2 жыл бұрын

That is the most important fact here. Once the cord separates from the plug, that is an indication of the stabilizing chemicals in the rubbers and plastic, have passed over the "half life" of their lifespan. All of the insulation at that point now begins to be suspect, and is actively deteriorating. Safety, and proper current capacity state it's time to replace that!
