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



I think you need to go into a bit more detail - it clicks but does it
play music? Are the clicks as you move the volume control or after you
have moved it and taken your hand off?

Yep - clicks as music played, as if a connection is loose, loud crackle,
and continue once hand removed. Slight occasional rustling noise when
volume set to zero. It's been on about 10 hours with no
improvement/deterioration. To add insult only one channel is working,
with both working when the mono button is pressed.

Ultimately Quad kit is well made and relatively simple. If you can find
the handbook it probably contains the circuit diagram so should be
fairly easy for someone competent in electronics to repair. Or you can
send it to Quad in Huntingdon where they have a superb service
department.

Yes - I gather, and if it was rare/loved I'd have it serviced. But as it
is it's not of any particular significance, and is quite old (sn 3942),
although it all looks new inside/out, apart from the volume knob. I
might get £30 on ebay making repair possibly uneconomic.

If the 'clicks' only occur *when* music is playing and you adjust the
volume control, then it does seem like a volume control problem. However if
you get clicks when you rotate the control without any music or input at
all, it may be a dc offset problem, not the volume control.

Jings! I'd probably pay 30 quid for it! :-)

Slainte,
