Special 10% log taper audio potentiometers?

formatting link

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.

Digikey list some Panasonic "D" taper pots on page 2083

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

I got potentiometers with center tap at
