Hello Douglas, Al, and Mofi,
Thanks for your time and energy.
Although I recall seeing the "squares" on the NE corners of the OpAmps after initial inspection, I can no longer rule out the unlikely. I have no illumination from within the unit - board, diodes, or otherwise - so if we assume one or more of the OpAmps were installed incorrectly, what is the likelihood that the entire unit, as opposed to simply the OpAmps, is salvagable (vs replaced)?
I realize more trial and error might be necessary to answer this, but my time to do so grows short (honey-dos, kids, etc.). Is there a qualified technician / repair shop that might be able to further diagnose / fix this - I have been unable to locate one?
Cheers.
