Really rare Alps Volume Potentiometer 33.3 kohm x 2, with click positions, step error only +/- 0.2dB !!!
It is New Old Stock, never been used and was made to extremely high standards special for use in Yamaha audio products but it can be used in many others amplifiers…
Another important thing… it is 33.3kohm, non-standard value, so really hard to find genuine Alps volume potentiometer!!!
