And the Doctor comes through yet again with a file from his Univac terabit archive.
Thanks, Doctor.
To the OP, this is a microprocessor based unit.
So you are basically stuck with verifying the analog portion.
First things first.
Check the power supply voltages on the unit (page 1).
I would also resolder the input/ output jack board.
If you get super stuck on the repair, Digitech will repair just about anything that they made.
They are easy to work with , so contact them if you feel the need.

Would it be possible to repost this schematic?
