Anyone familiar with servos, solenoids and relays in color tuners

I would expect that only the pots that those gears connect to can make the actual adjustments, and that those controls have to do with the alignment of each remote receiver circuit or the sensitivity of each circuit. But I would need to see a schematic to know for sure. The CTC-9 remote chassis doesn't have all those controls, just the adjustable coils for alignment and those are those are the ones accessed from the top, not the side.
