74 JMP with volume control issues. I’ve got a 1974 1959JMP that I just re-capped it had a few things done to the bias circuit but I repaired them. I fired it up and it sounds amazing but the volume controls are acting strange. When I plug into the bright channel theThe gain jumps when I turn the volume up to about one or two as if it’s on full and when I adjust the normal channel it works in reverse ( so turning up the normal vol cuts the volume on bright channel) so somehow the normal channel is affecting the Bright channel even when not jumpered. I was assuming a mixer resistor or a coupling cap (although the amp doesn’t display any other symptoms of bad coupler) but I haven’t been able to track down anything out of the ordinary yet. Anyone have any ideas on what could cause this symptom?
