    Cool Ampeg Gemini II Schematic

    I am currently working on a couple of old Ampeg Gemini II chassis, I picked up pretty cheap (chassis only) at a Ham radio swap. They both appear to be from about 1965 based on the serial numbers. They were missing a few parts most of which I was able to find. The large electrolytic can caps are missing on both. The schematic located in this thread:

    Ampeg Gemini II G-15 quirks

    appears to be correct but many of the values are unreadable. The rectifier in both are the two diode full wave type with PT 113A power transformers. What I am looking for is a schematic that is readable. I have seen the Joe Piazza schematics for the 7591 amps but they all seem to use the 4 diode full wave bridge with the PT 113B transformer. If anyone has a high resolution scan or knows where there might be one on the Internet I would appreciate the information.

    This may be a bit more 'readable'.

    Thank you for your reply. The values I needed are more readable on your attachment.
