I made a approximate PCB-Clone of the pedal,
since it will then be easier to trace the circuit
by use of the Sprint-Layout test function.

The circuit board of the TO-1 is the same as the one of the OVD-1, so I found errors in the schematic and layout OVD-1 by tracing the TO-1. The LED series resistor must have the designation R26 and not R18. R18 is the emitter resistor of T5 the designation R18 was missing.
The value of R8 was wrongly designated this is 10kOhms instead of 1kOhm. The values of R34 and R35 were mixed up.
The right connector of R7 was connected wrong.
Here the corrected layout and the corrected schematic:
