Mark,
I may do that. I've just had too many weird problems with it and I'm doubting this will be last I see of it. I don't think, though, that I'll do any scraping. The custom ICs have gold-plated pins.
Thanks,
Barry - N4BUQ

Barry,
You had a dirty contact on one or more pin(s)/socket/both. I will use IPA with a
brush on each IC and transistor on that board, move out, rock back and forth
enough to clean and scrape each then reseat. Unless you need or want to, there
is no need to replace any socket(s) that are not the TI problematic types.
Mark
