Default Flaky volume control QUAD 66

Cheers!


My old Quad 66 has a very flaky volume control: sometimes it works fine,
sometimes not. All other controls on the remote works fine. The volume
control signals does not seem to reach the pre-amp, as the display does
not react. When it does work, the display and gain is synchronized fine.
I'd rather not send it off for service, as it probably cost more to fix
than to replace with modern gear.


I'd suggest asking quad as your assumption about cost may be quite
inaccurate. :-)

Slainte,

I have recently repaired a 66 Remote and can tell you that there are two
I/R codes generated by the Remote. One is RC5 for the CD and Tuner and the
other a special Quad code for the 66 pre-amp (e.g. Display ,Tilt, Input
selection, Volume & Balance). It sometimes happens that one one code works
and one does not, but this doesn't appear to be the case here.As it is the
volume control that is intermittent,it is very likely the digital rotary
pot is faulty, however it may also be the IC for the special Quad code that
is borderline. Note that this IC has to be optimised by tweaking a trim pot
and Quad have a special jig to do just that.
You have a couple of choices - 1)Get Quad to fix it - cost about UKP48.00
plus parts or 2) buy the smaller alternative remote from them for UKP35.00
plus P & P. Your choice as to which to do.
