Hi. I try to repair this amp. Everything work fine, without left channel. I have only trebel from speaker. If i switch on source direct, everything work perfect? Any suggestion?

mastertech: Not finding much. Maybe get the part numbers off those 2 devices mounted on the heatsink near that resistor. Sept 15, 2023 21:03:01 GMT -5
