The "precision double potentiometer" is described as for "Audio Amplifier Volume". I ordered two of them: one measured 50 KOhm, the other one measured 44 KOhm. This is not really "Precision". But both potentiometers are unusuable for a stereo amplifier, because the two channels of the double potentiometer have totally different characteristics. One channel seems positive logarithmic (that's what you expect for a potentiometer marked with "A" letter), but the other channel has a completely different characteristic (more similar to negative logarithmic). At least I am glad that I have measured them before soldering them in.
