You have touched on a key issue and that is parts placement. Just because
the knobs are in nice symmetrical locations doesn't mean I can get the
circuitry where I need it. Currently there are 8 trim pots on the board and
I require them to be placed on the edge of the PCB so the thing can be
calibrated while it's assembled. The control pots are now right where I had
the trim pots, so needless to say it's becoming a PITA to get these placed.
Still working on it with some alternate pot placement...
