Peterson 450 strobe tuner

[MichaelNuzum]

Hey all- does anyone have a schematic for the Peterson 450 strobe tuner? I have a dead one on the bench. I have been able to diagnose a faulty 1N744A zener diode, but there's still something else wrong with it. I can find the model 400 schematic, but it is a very different beast. Thanks in advance for any help.
