Hi and happy upcoming weekend to all I have this sansui 9090 in with the protect light flashing. I disconnected the power supply to the outputs by removing the fuses. The light went out. I checked the outputs and none were shorted or leaky. I checked the pre amp board and that checked good with no leaky or shorted transistors. There was an open thermal fuse on the heatsink of the outputs. That was open. I replaced with another themal fuse of about 120 degrees since that part is no longer available. Does anyone have a print available? and or any other ideas?
