     Would anyone be interested in a PCB set for this thing? If Marc
is okay with me doing a layout, I'd love the chance to layout
something like this. I thought about it last night and came up with
the idea of splitting the design into two PCBs: A power supply board
and a VU meter board. That way if one wanted to do multiple channels,
one PSU board plus NxVU boards could be used. I'd add on a
differential receiver to the VU board so it could handle both balanced
and unbalanced signals, plus a rubber retaining grommet to hold the
nixie tube in place.
