a friend of mine had recently bought this amp and the second he hit the power switch the left channel blew, so the seller took it back and "repaired" it and sent it back, only to blow up again in a matter of seconds, so i told him to send it to me instead.
obviously its been smashed in shipping bent upper right corner of the faceplate, and right lamp holder is broken. I will take the faceplate with me to work (mechanical workshop) and see if i can fix that up a bit.
upon inspecting the left amp i found that the outputs are fine, there has been a fire ( 3 resistors) on the pcb and components actually fell out of their holes due to previous techs poor soldering, there are broken tracks, soldering that looks like short circuits, all transistors looks to have been pulled probably for checking and then put back, i have to go through them all to see if they are in the right place
really dont know where to start out here im just looking at the thing and shaking my head.
part of the fun in this hobby is you never know what you will find inside this stuff when opening them up
Q731 (Diode) fell out when i turned the pcb upside down. 3 resistors are burned and a short in one of the drivers.
underside of Q711. pretty much looks like this everywhere that service has been made
