When I first got my LP-Pan and read the manual (doesn't everyone do
this?), I found it strange that the audio outputs had the ability to
lift grounds (apparently to reduce noise/ground-loop issues). I
guess I must be doing something right as I did not encounter any hum
or noise issues with audio shields grounded.
In the early years of building radio-computer I/F boxes (HB) it
became quickly evident that isolation transformers solved a lot of
these "grounding issues".
I read your presentation, Jim, and gives me a laundry list of things to check.
