Hi All. Hope this is in the correct section. I'm repairing a BX4500. Power amp (P3000) has a big difference in the voltages of the power rails. I've re-flowed solder to all caps and transistors, checked all diodes, measured caps with an ESR meter. I'm about to throw it against a wall. Anyone have any good tips of where the issues may be? Schematic attached with measured voltages. Thanks for any help.
