Wow, great video. I have a 65 Deluxe Reverb reissue from 1996 with the exact same problems. Really loud hiss and crackle on the reverb knob. Just dropped it off with an amp tech, but this video at least makes me feel that a fix is within reach. Thank you! I learned something new today.

Exactly what owners need. Simple understanding of some issues. With simple solutions. Proves not everyone doesnt just wants money out of you. 👍👍

Caught you on Tone Talk with Dave Freedman. Happy to see you schmoozing with a guy who really seem to want to see and help you take off with your amp builds. So cool he actually watches you channel. Love it!

its quite dark in that reverb tank :)

Thanks for this, Lyle! I was able to get my Princeton clone (Clark Kanee) as quiet as my noisy house circuitry (50's house with more recent dimmer switches everywhere) will allow by hot swapping in preamp tubes while I had a dB meter app going on my phone in front of the amp.

I have a Princeton reissue that needs the caps replaced. This video gave me the motivation to finally get off my butt and do it. Thanks...

Thanks for making this video. I kept getting told that noise was normal in my 65 re issue. Soon as I get my stuff out of storage I'll contact you about bullet proofing it.

It's also a good idea to make sure the tank is the right way round. The output of the tank doesn't like being near the transformer.

What a coincidence that it's also the best amp ever made too, ever...IMHO of course.

Looking forward to the follow up!

I recommend people with many amps and techs to get a Orange Divo VT1000 Tube valve tester. It has saved me lots of money and trips to the repair man.

Thanks, I love watching all your videos on amps. I just had a question about the hot rod amps, is it worth it at all to swap out the little metal feet for rubber ones? Would it help with vibration and maybe preserve the amp a bit longer? Apologies if this is a stupid question.. thanks again!

I wish I lived near enough to get my Deluxe Reverb Reissue to you! I’m in UK. Have some Ok local techs near me but no way they take the same care over their with or have the level of expertise you do

Thank you for doing these videos. As a owner of a few old amps. :)

Great stuff...I wish you were in Montreal. I have a Blues Jr. III thats working fine, but it's beeen used quite heavily and I'm sure would benifit from your mods and maintenence. I'm using preferred series 7189 tubes that can handle more juice, but cooling the bias seems like a good idea. I put a Cannabis Rex speaker in it and I think sound is overall way better. In your opinion is that a good speaker choice for that amp?

Interesting. A PR build I did from of an Ao29 with all new components had the same exact issue with the reverb. Sounds great till turned up to 6 or so. Then a bit of hum. Nothing I did fixed it. I didn’t figure it could be the brand new MOD tank!

Cool info😎👍

Great video! Did the tank replacement also eliminate the crackle in the reverb pot?

5:13 "Crackle and hum". Wasn't that a U2 album from the late '80s? LOL, sorry, couldn't resist ;-).

Never knew you could drive a speaker from the reverb out!

Another great video, enjoyed it. Is it possible to use the reverb input and output as an effects loop?

Beautiful. Ty.

I have a PRRI as well, and have been having it cut to a way lower volume and will usually mostly come back in a bit. I took off the back and turned the amp on and notices that V4 is glowing a lot more than the other preamp tubes... i'm thinking maybe that is the problem? Thank you!! Great video btw!

So can you dime the volume when using the reverb XFMR to 8 ohm speaker (whilst seeking OD & distortion) with no worries concerning the main output to ground (?) and also is there a safe way to route the rev. out to low level in with some sort of simple/easy impedance matching (if necessary) also for chasing distortion 😵‍💫(?) (Thanx in advance) 🥸

What speaker would you suggest for a 70’s Princeton?

I’m having a very similar issue with the reverb on my 94’ Twin. Was there a particular reason WHY the tank went bad on this one? Any apparent damage? Would a tank be fixable or should one just attempt a swap?

Hello Psionic Audio. What would you do in my situation? I bought a Carmen Ghia that kept buzzing and humming uncontrollably, and sound cut in and out. The one they sent as a replacement had a volume knob that wouldnt shut off too. Never experienced issues with any tube amp or brand like this, and was wondering if its even worth the 6 month turnaround wait for me in Ontario 🇨🇦 here. Thanks for all the great learning! 👍 MJ

Thank You

I’m thinking about buying a new 65 DRRI. Fender offers a 64 Custom Deluxe Reverb for twice as much. Does it sound that much better? If I go with a 65, can you recommend a tech in SoCal to replace bad stock components?

Liked and subbed

I used to have a DRRI '65 and when I complained about the always existing hum (which was pretty loud when using tremolo and reverb) everybody told me it's completely normal! So it wasn't?

I have a re-issue fender Deville 4 10 in speakers sounds like dust really static then blew a fuse should I take it to a shop or just replace the fuse and do nothing but blow out the cab with my air compressor

I have a 5E3 that tends to eat 6V6 power tubes. Is that common for this circuit? Thanks.

Can you place a light in the reverb tank? I didn’t see a thing.

I have a brand new princeton, second one actually. First one had a rattle on low notes at reasonable volume, second one does it too but the warranty tech doesn’t hear it. It’s a 1200 paper weight at this point. Should I start replacing tubes since that is what the tech said is common issue with new amps But do I replace them all?

Make sure the cab/baffle screws are tight, but it’s probably the JJ 6V6s not the amp.

Does Fender make any reliable amp in 2022 and what lifespan do they have?

Don't forget Princeton is single ended and will always have more floor noise than a push pull amp.

Hey Lyle, I'm hoping you can help me understand an issue I'm having with my Deluxe reverb after making a really idiotic mistake with it. I sometimes use a Marshall head into the speaker of the Deluxe (just using the combo as a cabinet, deluxe reverb stays off.), and accidentally grabbed the wrong cable while running late to a gig and mindlessly plugged the speaker out of the Marshall into the speaker out of the Deluxe Reverb... I noticed no sound and turned the amp off, it way on for maybe 30 seconds to a minute tops before I realized what I had done. The Marshall made it through the gig and sounds fine... but I just got back home and plugged the Deluxe Reverb in, and it's sputtering and signal is cutting in and out. Do you know what issues I could have caused by doing this? I plan to call my tech about it soon, but right now am just so embarrassed and defeated by making such a mindless and stupid mistake. :/

What Hum??? Your audio is very, very poor for this kind of demo - And YES I have my PC volume at full bore. :-( The first few minutes are useful to know after that there isn't much of practical use for an amp owner... well of my limited knowledge anyway.. The reverb driver trick: Input is actually the reverb Output... thus it can be hooked up to a 8ohm speaker... for low output practice, hmmm... Well I guess that's handy to know without any explanation. Then there is the ability to plug your guitar directly into the reverb driver but with impedance issues... again no explanation. I guess that would have meant a much longer video but, maybe if you are bringing it up you should perhaps direct viewers to more info. When you arouse curiosity... people like answers.

@michaelkrailo5725

The main point of the video is that you shouldn't hear any hum when all the knobs are turned down and nothing is plugged in (also when the knobs are turned up as well). He fixed the first issue by swapping out the preamp tube, so that was a simple fix for anyone to do themselves. The second issue was hum that occurs when the reverb volume is increased. It was audible in the video, but probably not as pronounced as you would notice in person and it's not easy to pick that up without placing that mic really close to the amp. There are many reasons that would cause this issue, in this case it ended up being a bad transducer in in the reverb tank. Unfortunately, you need a new tank to even test that but it's good to know that's where hum can come from. As far as the low output trick, you have the option to connect an 8 ohm impedance speaker up to that reverb tank output and play at lower volumes without reverb. Do not plug your guitar into that jack, that's for the speaker only. Your guitar plugs into the normal input jack on the front of the amp only. Of course, the main volume knob won't be used and only the reverb volume would be used if the goal is to play at a lower volume level.
