I've just finished my own MSPQ76 but I have some issues:
All the voltage are good from toroid to main board.
I made all the mods from the "Errata" book.
But when I turn the unit on is like my gain pots are reversed... And I have a very little sound even if I push them max
In Bypass everything nice.
I changed the gain pots by 22k lin as you said, maybe I wiring them bad, could you help me please?
Reverse pin 1 and 3 on the gain pots from what you have now.
Make sure you changed the resistor values as well as the gain pot in accordance with the (non-critical) errata.
Also, check your filter board wiring (1 goes to 1, 2 to 2, etc).
Some people try to go by colors on the wires and make it out from the pictures - this is NOT recommend, and it seems to be the main cause of errors.
