Alps and Bourne pots are junk ,2 plastic wipers with a conductive spray on them $25
where any good volume pot has a resistive ladder and then relay controlled
which the Khozmo has I have used them before .
I replaced the volume pot on my tube preamplifier.
Replaced the two mono Alps pots in phono preamp with Tocos (Tokyo Cosmos), RV24 units. I heard good things about these pots on other forums. Fair bit of work getting them to fit into the Croft 25R. I had to loosen the tube boards and drill out the mounting holes for the larger threads. The pots were only $26 for both inc tax and shipping. Huge improvement in speed, clarity, solidity, and transparency. I'm blown away.
