Hi guys. I have a JMP I bought early '90's. Seller said it was modded by Frank Levi and actually supplied his contact info. I didn't know who Frank Levi was at the time, but the amp sounded great and I bought it. I've replaced tubes and filter caps over the years. I also added the no loss FX loop, which did not change the tone of the amp what so ever. Recently I fired it up and there was no sound. Only one tube was lit up, so I quickly shut it down. I thought I had lost a 6550, so ordered a new pair. Pulled the chassis from the cab and installed new 6550's. Still one tube did not light up. I could smell "that smell". You know, the "something is cooking" smell. I shut it down. I found one of the mustard caps to be very hot. It's the one marked with red tape in the pic.
So, I need some help. Could the problem be the cap? Or, is the overheated cap a result of some other issue?
Also, does this look like the work of Frank Levi? It seems very messy and hacked to me.
Thanks in advance, and let me know about the mod as well. I have a good mind to grab a schematic and put at back to original spec...However, it has the best tone of any amp I've ever owned.
