Re: Grundig TK 819 Any Useful Info
Very carefully manually drilled a small hole in the back of the mains on/off switch. First double checked that the switch operation was the same as before, i.e. both switch poles permanently made and mechanical operation feeling/sounding good/normal.
Low and behold, after drilling the hole the switch then worked normally, mechanically and electrically (both resistance and voltage wise).
Tried it numerous times and it was 100% good/repeatable.
For good measure sprayed a little Supersolve Super 10 into the hole (this was the original plan anyway) and operated the switch a few times, but now the switch never switches on electrically ! and mechanically you can feel/hear that it is not now switching on when turned to the On position.
May not have been the Supersolve that killed it, maybe was just the extra on/off operations. Will keep exercising it, in case it comes back to life but pretty sure it is now dead.
I have a toggle switch ready to install, if the switch does not recover.
