Heh heh, Could I ask why to solder in crystals? I am pretty sure U5 is fried. If running for 5 minutes it becomes HOT. I can still touch it but with no draw on it that isn't normal. The voltages coming into the board are at 4.88 volts and -14.58 volts unregulated. The -14.58 volts goes right to the volume control so under any circumstance that isn't the problem. The 4.88 volts is all fine to the chip so who knows. I will be replacing sockets and U5 soon.
