Can of worms warning!

Should the PCB be laid out so as to allow PCB-mounted pots for
perhaps 4 or 6 of the controls? Different front panel formats could
be allowed for by simply doing point-to-point wiring instead of PCB
mounting the pots. The difficulty comes in deciding which format
would be used to dictate the spacing of holes for the PCB-mounted
pots. Both Blacet and MOTM have standards we could appropriate for
PCB-mounted pots. The CVS' pots (as spelled out by Grant) are grouped
in functional units of 4, and that is the typical max vertical
allowance of pots on an MOTM panel. Blacet has up to 6 maximum, but
plenty of designs have fewer pots.

I guess someone had to bring it up.... :)
