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.

No reason to keep experimenting. :)  I was just curious what you liked so much better than the famed Alps. :)

Ah, interesting.  I wasn't sure I thought someone made a discrete mini pot with surface mounted resistors.  Glad your experiment worked out!

So you went from ALPS with wipers to discrete ?  How old were the originals?
