Does anyone know the secret how to open old Gralab 450 darkroom timer for repair?
I have one with small slide switches (not membrane ones like in newer 450 and 451) and they are not working 100% of the time, requiring fiddling and switching them back and forth.
It seems to be an easy project to get them replaced, but I have no idea how to remove handles from rotary switches, they must have been glued on.
Hopefully I'm not the only one trying to fix things instead of throwing them out
