Hi all,
I'm repairing an old italian stereo amplifier and the volume dual
potentiometer is scratchy beyond any hope. I tried cleaning it and then
also dismantled it but the carbon part is too much ruined with several
pits. Also the two channels doesn't really track anymore, having large
differences in resistances in almost all positions.
The problem is that these potentiometers (47Kohm) have an extra fourth
contact
which is at fixed position at 10K from one end. It's the first time I see
such a potentiometer with fixed divider. Does anyone know how to source
a suitable replacement?
Thanks in advance and best regards


Those are not at all rare on Hi-Fi PAs - there should be component suppliers
around that specialise in parts for consumer goods.

The best I can suggest is search the biggest newsagent you can find for
trade publications, you may find addresses of suitable supply houses.

In the UK, we had Television Magazine & Technology_at_home - sadly, both
went down the gurgler some years ago.
