Hi

Does anyone know where I can source a good quality rotary switch (2
pole and 20 ways) to make a stepped attenuator??

I've looked at previous posts reccommending Blore Edwards but I can't
seem to find them on the web....maybe they're not trading anymore??
Farnell and RS gave me no joy.

I've got a home made amp and I'm currently using a conductive plastic
pot but I'd like to hear the difference in going to a stepped
attenuator.

The classic switch for this in days of old would have been a Painton part.

You might try an Elma switch or maybe Grayhill.
