Re: volume dial
Yes it could be easily repaired,I had a loose volume control on
a previous 166 ,and when I tightened it up I noticed it was a standard rotary potentiometer type,no doubt available from the likes
of Maplins,it would entail removal of the ICS(covered on here in detail),but it should be relatively easy once its' out to remove and solder in a new component,you certainly wouldnt' need a new ICS,
anyway if you do need a new ics they turn up on E bay from £100.not
the £1000s' quoted by dealers,just make sure you get the code card!
