so for the past 3 months or more i've had my amp out of the shell because i had to perform a fix on some wiring that didnt hold from a previous fix by randall's repair shop. i got lazy and didnt put it back in the shell until last night for band practice. i had been playing through it regularly and everything was fine, but after loading it into the shell and turning it on, it popped and smoked. i took it apart on the spot and didnt see anything wrong until i looked at a module that was in the middle socket (socket 2) of the amp.
the 2 resistors (i think r5 and r6) all the way at the top left, if your holding it with the knobs facing you, were charred and 1 of the 2 little black things that stick out of the pcb were damaged. i dont know what those are called but its basically 2 leads that stick up and have a plastic cover over a metal plate. the plastic cover is what blew off
so i figured the module was bad.
i put the other 2 modules back in and left the middle socket empty. i got perfect sound from the first module but the button did not switch to the 3rd socket. i figured this was because the middle socket was empty.. so i turned off the amp and moved the 3rd socket's module to the 2nd socket and boom. it blew out the same resistors.
any ideas? my only starting point is to take everything apart and see if there is a bare wire touching anything... since the amp worked perfectly until i put it into the shell. I hope to god i can just solder in some new resistors on my two dead modules now.
all of the fuses (didnt check the ones below midi board yet) are in tact
ive really had a lot of headaches with this amp and i'm considering fixing it and selling it, and at best getting an rm4 or maybe just another brand all together
