I've just plugged in a Quad 34 preamp that's been unused for a few years.
When I turn the volume control up there's a series of loud high pitched
clicks through the speakers, a bit like LP static discharge maybe. It was
fine last time it was used.

Does this sound like an expensive problem, or would I be better off
punting it on ebay, and buying another (about £80 it seems)?

Thanks, Rob

It is the volume control that needs replacing. It's a very common problem
in most audio circuits of that age and the design of the control doesn't
help. No need to bin the preamp, just find another volume control.
Maplin will sell something suitable for around £2-3. I would solder it in
or
get a friend who can - you will save a fortune.



OK, thanks. Thing is, it looks to be quite a unique part - Alps, with a
nice feel and little indented bumps as it turns. However, I'd be pretty
certain that they're available somewhere. I don't think I'd do it
myself, and there might be a 'good money after bad' type situation
building up ...
