Just measured a PEC potentiometer 50K with a output source of the amplifier of 500 Ohm. Capacitive load 100pF.


This is the worse setting at 3 o'clock



Measured at 12 o clock setting



And this is measured at the 9 o'clock setting
Looks "bad" but look at the scale, about 0,2dB 0,3dB differances.
