I'm fixing an old amplifier (Mission Cyrus StraightLine) replacing the
20K dual gang volume control. It looks like a fairly standard 17mm PCB
mount job, but I can't locate the D-type / 10A logarithmic taper (10%
value at 50% rotation) of the original part.

I'm guessing a 15A taper (the standard logarithmic, A-type) would
probably be unusable at the low end of rotation - I've got a loud source
and sensitive speakers - but have ordered one from eBay just for a test
on that.

But who sells the 10A logarithmic types of a decent quality? I'm in the
UK* but will do international purchases.

*have tried RS, Maplin, CPC, Farnell, Rapid, eBay. 0/10 so far.

Get inside the pot and run an resistor of 10 percent of track ohmage to the
mid point, submm hole through the paxolin to anchor or use SMD and silver
paint to bridge the gap to the track, not true log track but good enough for
most porpoises for totary or slider pots. Now log wire-wound ones are more
fun, tapered formers and change of wire midstream
