Soundstream XTA-480.4 repair help needed
I have a Soundstream XTA 480.4 amplifier and have had it for many years. When I got it, only 2 of the 4 channels worked. Tried to power it up at one point to attempt to troubleshoot and fried a resistor on the board. Been trying to find a schematic for years with no luck. I am not new to electronics but not sure where to start. tools that I do have access too are adjustable power supplies, meters, irons, and possibly an O scope (I am product manager for electronic medical devices) Any help would be greatly appreciated.
