There is a printed resistor board that brushes rub on. There are two
pads that must have good contact for each manual shutter speed. It's
possible that the low manual pads were dirty but then probably all the
pads needed cleaning anyway. Dirty magnet would wildly affect all speeds
auto and manual. A 3/3Ti could have erratic slow speeds due to the slow
speed governor, not the same in an electronic camera (as you pointed out).
