My Bolex's (rex4, i suppose!) MOT/0-knob is at "0" and the motor is still running. I can't even turn it to "MOT".
Of course, there's no harm because the motor runs! Luckily it's not the other way around.
Just wondering what might be the case.
Probably I can't now use the MST with it or rewind the reel but I have a fully working REX5 so that's not a big deal.
