Rob,
Thanks for your detailed answers and explanations. I'm primarily and
EM pinball guy, so much of the detail is a bit beyond my knowledge
level, but I'm trying.

The box I have is a 1454, and I'm wondering if it might be a whole
lot simpler to get a remote volume control. Do you know if RO made
one for this era, and if not, would it be as simple a wiring a
additional volume pot in series with the one already connected?

Thanks again,

Mike in NJ
