It should be pretty easy to find most of the components, there's only on LM324, and one transistor.  By tracing from the major parts, you can identify most components.

I have looked at this for a while and do not see any means of varying the output voltage, am I missing something? Also, the title shows "POWERHOUSE 180" not "CW-80", are they the same thing?

The LM324 is a simple op-amp, it doesn't get programmed.a  However!  I posted the wrong diagram!

The programmable part in this picture is the MC68HC908, if that part is bad, you're out of luck.  However, the failures are far more likely to be at the top of the diagram, specifically the BTA24-600CWRG is a likely failure candidate.
