Well, my Rem started blowing power tubes some time a go (one month, as long as I can remember...). I took it to a reharshal with some friends, and it started making weird noises. It was loaded with Tung Sols, no longer than two months in the amp... I noticed they were redplating, so I swapped them for a set of NOS Russian ones. After two weeks, last Wednesday they blew (two of them, always the ones in the middle...), and I swapped them for a fresh set of JJs ( that's a lot of dough on tubes, but that's it...). Yesterday, it started to make some strange noises again, and I decided to stop using it and take it home to check if something was wrong. I was a bit scared, as the Spanish dealer is very far away, and I wasn't sure if they'll take the amp for a repair. I opened it up, and, to my relief, I saw that one of the filtering resistors (please, correct me if I'm wrong) had a crack in it, and the surroundings had marks of overheating (I had smelled something burning the last day I turned the amp on ...). Now I'm calm, I know it seems an easy fix for a tech, but my question is, any other things to check besides the resitor? here are a couple of shots: And now, my last question: Does MAZ stand for Michael Anthony Zaite? Did Doc's son made my Rem? Yeargh!!!! Please, if there's anything I should tell the tech, let me know. Tons of tone!!

You have a couple of components damaged there. The resistor is obvious, but you have not noticed there is a component that is blown completely apart - looks like a capacitor (I've seen them do this before). You need a tech's help for sure.

Sorry to hear of this setback, Andy. Hope you get the Rem back in order soon.
Not sure about the MAZ. Certainly are Z's son's initials.

Thanks a lot, Steve. I found some pieces of what looked like 'metal film' and carton when I opened it up, so I think you're right (as usual ) with the capacitor issue. Actually, I did not know what that 'loose wire' meant... Thank you very much for the help. Can anyone post a picture of that part of the circuit with the capacitor as it should be? I think that'd be helpful when fixing it. Thanks a lot. Mike, thanks, I hope it'll be ok soon!! Tons of tone!!

After checking out a picture of the circuit, definitely a capacitor was blown too... Thanks for the info, guys!! I'll keep you posted. Tons of tone!!

Here ya go. The components in the yellow circles should be connected to each other as one unit (capacitor), and should look exactly like the black capacitor in the red circle.... the yellow dots show where the cap used to reside before the explosion......

Thanks a lot, Lee, sure it's gonna be useful. Now My main concern is why it's happened... Anyone has any idea? I've been told that too much tension could cause it, but I don't know why there has been such an oscillation in voltage... Thanks again. I've talked to the tech, and he doesn't know either... Anyway, they're quite busy now, and they can't take care of the amp until April 30th, so I have a whole week to find out! Tons of tone!!

You always hope they won't, but reality is a bastich... That said, make sure all of your tubes are good. Shorted tubes are real hard on components that are connected to them.

Thanks again for the advice, Steve,I'll have the tech install a fresh set of new tubes, PI included... Tons of tone!!

Well, I could finally take it to the tech yesterday, and he had a quick look at it. The grid resistors in V1 and V2 had symptoms of overheating, and maybe the problem started there, in the tubes; we hope it's not a tranny issue, let's see how it evolves... Tons of tone!!

Any updates?

yup, great teamwork here! Any updates? Not yet, still in the shop waiting for some caps to arrive... I'll post the updates as soon as it's ready! Thanks for the concern. Tons of tone!!

I finally picket the Remedy up from the shop yesterday, after the repair; both resistors and caps have been replaced, as well as the grid resistors of V5 and V6; the amp sounds as awesome as usual! The tech reccommended (just like The Doctor ordered) using only JJs, as they are run very hot and over the specs for a regular 6V6, so stick to them, guys!! The tech said that he really liked the amp's dynamics and the possibility of blending both channels, not to say the power reduction circuit. He also made compliments on the circuit and construction, so, congrats once again, Doc! Now I'm amped again!!! Tons of tone!!

Hi, This is my first post--just joined today. In August, I got a 2010 Remedy from the original owner who had sent the head back to Z for the Master Volume/EQ bypass mod. It sounded pretty good when I bought it, but I knew it needed new tubes (he had never replaced them, but I assume Z did during the mod?). I was playing last weekend in practice, and the sound suddenly cut in half, and I smelled a horrible burnt plastic odor. I turned if off immediately. I assume one of the power tubes red-plated and fried. I bought a new matched set of JJ power tubes, but wanted to look under the hood before installing them. It's a good thing I did! It looks like 4 of the resistors have burned up (are the brown ones screen resistors?), and the two tube sockets involved are a little charred. See pictures below. Can my tech simply replaced these 4 resistors? Do I need new tube sockets, or can I just clean them with a little rubbing alcohol and contact cleaner? Do I need a new fuse? Suggestions?

I'd recommend a trip to a competent tech for a thorough check. You may also want to repeat your post/inquiry in the amp troubleshooting section as it may get more views there. Make it a new thread. And welcome aboard!

Thanks guys!
Seeing as I'm new to this, would you suggest starting a new thread in the Amp-Troubleshooting page, or posting to an existing one?

Thanks guys! Seeing as I'm new to this, would you suggest starting a new thread in the Amp-Troubleshooting page, or posting to an existing one? New! Make the subject relevant to your specific issue - that way people who may know something about that are more likely to read your post.
