- This amp came in with an issue when using the tremolo. After replacing a few parts and changing out a bad output valve the amp sounds as it should.
I found some helpful information on this site as well and would recommend checking into it if you need to work on one of these.

Hey man. I’m gonna miss you in GWAR. Seems it was in good terms. Good luck on your next adventures. Rock and roll. 🤘😄
I really like the reverberocket and super rocket from this series.
Hey fantastic video, thank you! I recently stumbled on some of your speaker wiring videos while upgrading some cabs I have. Thank you so much for the clear and instructive content. It's awesome seeing someone who clearly is knowledgeable and that takes pride in their work, help out other people that may be having similar issues.
Glad to see ya posting more stuff. Love the content.
I have this exact amp. I need to send mine out to you!
We all would like more tail.
Every time you get into the techspeak I think of the Rockwell retro encabulator skit
I had to google that, never saw it before and now I can't get enough of it. Thank you!
@@purgasound it’s a gem. Thanks for the upload!
I just picked up a 2002 J12T with the same noise you described. Put 2 new matched EL84s and still have the same problem.??
I had sent to me to brand new two El34 and they where microphonic and they had been tested before shipment. May be they where not tested for microphonic but OK on their tube tester, got a full refund.
What I do not understand is why are you spending the time to try to match an old valve with a new one? Would it not be better to just replace them with a new matched pair and be done with it? Give the customer back the old valves and at least one could be used as a spare in an emergency. If the customer is not willing to spend the money on valves, then maybe they should just get a Katana or an HX Stomp. Did I miss something, and you did put in a new matched pair?
@@shane011471 Customer wanted to save some money. Sure, new matched pair would be great but I've had plenty of brand new tubes fail so it's never a "be done with it" situation. I would rather utilize stock than let them sit on a shelf. Just this month had a brand new EL34 arc when bench testing and another pair replated on their first operation.
Next time a client brings me a tube amp I'll be sure to turn them away and tell them they should buy a Katana or whatever. lol cheers mate.
@@purgasound My comment was not directed towards you in any way whatsoever. Yes, brand new valves fail from time to time as for a lack of a better term "Shit Happens." To just replace one valve makes no sense at all as they will age at different rates, how old is said valve? Just because it tests fine today does NOT mean it will test fine tomorrow. I do not care if the customer brings me the valves "I just do not warranty them" OR they purchase them from me as I do not care at all. I will NOT just replace one valve as it makes no damn sense to do so. How could you even argue this is beyond me TBH. Just like I will NOT do top side PCB repairs. If you are unwilling to spend the money to do the job correctly you can go someplace else. Once I take a repair in MY NAME is now on it and my name is more important than money. This has worked out well for me as there is NO point in doing any job half assed.
@@shane011471 it's all good, my friend. Cheers
Do you do anything solid-state? I have a randall rg80es snakeskin that powers on and makes noise but sounds like death. I'd love for someone to fix it
