This came to me with low volume. A quick look at the tubes showed the PI only lighting one heater. I tested it on my tester, sure enough, it's dead. A new tube fixed the problem - until we put it back in the cabinet. Now the #3 & 4 (overdrive) channels won't work right. They have volume but no overdrive. WTH? We didn't touch anything underneath when putting it back in the cab, and it worked perfectly right before doing so.
There are so many chips and circuit boards in this thing, I have to ask Bruce - what the hell were you thinking when you designed this one??? You can't even change two of the power tubes without pulling the chassis. I have read so many nightmare stories about this series it's not funny.
