Default Quad 34 Problem

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.


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.

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.




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.


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

Slainte,

Jim
