What to replace trying to repair it on the blind. I.e. No schematic, and NO way to test it.

Went through all the solder joints and traces. Touched up a few joints. All traces now have continutity.

Circuit has a total of 6 electrolytic caps. I'm going to take it to work and check them on an LCR Meter we have.

Now. There are 3 unmarked BJT transistors on the board.

There is a 40 pin DIP IC Marked ITT V8001-501, haven't been able to find any info about it online. but the top edge looks a but suspect - swolen.

There is an LM2091 Quad comparator on board. and a bunch of xener and regular diodes, as well as two pairs of heat shielded FET's that are setup in a Darlington Array.

I can post a high res version of the circuit, if anyone would like to see.

If anyone has an older reference or catalog, I would appreciate any info on the big 40 pin IC.

Take care,

George
