That's some way to treat a customer. :-/
Such are the pitfalls of board-mounted pots.
Given this situation, Paul, would you design things differently if
you were starting over? Say, use a daughterboard for the front panel
components? Not sure how useful that would be, though.
Roger Arrick's approach is interesting. For those who haven't seen a
"dotcom" module, the pots (24mm Alpha) are fitted with 3-conductor
pigtails terminated with small MTA connectors
(
http://www.synthesizers.com/technical.html). PCBs have the
complimentary MTA connectors on them. This makes it really easy to
mount and replace pots (which will ∗need∗ to be done, some would say,
since the pots are not sealed on S.com modules). There is the extra
expense of fitting the pots with pigtails and connectors, but you
avoid flying wires between the front panel and the PC board. The net
result: panel-mounted components without soldering any wires to circuit boards.
I'm not suggesting that Paul adopt Roger's approach. More like I'm
wondering what the MOTM community thinks of it.
Naturally, there's no perfect or best solution -- you just need to
pick the set of trade-offs that works for you. Cost / convenience /
reliability / non-obsolescence / etc...
