Repeatable turnover options would be the bomb, given that: one starts with a good idea of which curve should be used for a given "label"; there is a good way to keep track of where the thing is set, relatively speaking.
If twiddling aircap vanes, any relays, servos, etc. should be properly geared (low...), with a very accurate vernier and no lag or "over-run", and they should be kept out of the electrical matrix.
Remote or no, I do not see this as useful for tuning on-the-fly unless one is switching between label years, or the like, and in this case it would probably be best to use VR, even hard switching. Again, the switch itself looms large in this sort of loop. With hard, on-the-fly switching, a null-mute would be appreciated, and maybe even necessary.
My TAP pre-amp uses industrial computer relays; very reliable, dead quiet, and out of the loop, with separate PS.
