My Bill Beard needs a service - tube sockets need replacing, potentiometers need cleaning etc etc.
But I have a problem - how do you remove the potentiometers used as balance controls? See the pictures below. The first shows what looks to be a clip.
The second shot shows the back. There is a nut underneath the pot but it is pretty inaccessible - I have no tool that can get behind it, and if I did, I couldn't move it much.
There are two such pots. They can't be cleaned as far as I can see, but the wipers are in a bad state.
Question - how do I get them off the chassis? Remove the clip? If so, how? Are there special tools for it? A screwdriver is risky (I have tried) and I don't want to damage the chassis finish.
The blue Alps pot I have disassembled and can just prise open to get at the wipers with some Deoxit.
