Well folks, Good news. I checked out all the components, did a re-flow on the pots a couple of joints, and plopped it into a larger enclosure, and it works much better. Erm, the wires are a bit long on the pots, oh well…
Prolly dinged something jamming it in the smaller box, or the re-flows improved something or other.
Anyway, thanks!! On to the next project!
