There is a CT27G33 Sam's Photofact in the download area on the active list. The power supply section is essentially the same. Only "A" type regulators will work in this circuit.

Q801 also leaky base to emmiter. The protection diode appears to be ok in it. Opto isolator checks good. Still dead though. Although someone did give me a few ideas. Someone else also recommended I get a print . Where would the challenge be then? Just teaseing, it was a good idea I may yet have to subscribe too. Someone did tell me a little about how it operates overall. I'm still open to suggestion on it for sure..
