With pot size matters
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.

Yeah, yeah...heard it before..... @bolong ...Yup, ask the lobster at your next gastroventure...;) @noromance ...(Surely you jest? ;) Always wanted to ask that and "NONE?!" *LOL* ...and then, consider it as another PS as keeping it under control and put to Good Abuse...🙄 It's bad pot stories in bigger $ pre's and amps that drove me to near-total digital switching with my picks for twitch...nothing wears out or dusty, leaving me to get corroded.... The matrix switcher is the only exception, but due for some TLC... |
@bruce19 Kindly follow up when you make the modification. The Black Beauty RK40 is not in production but there seems to be some online. |
@asvjerry Huh?

Primaluna EVO 400 Pre Volume Pot Photo This is the pot in my tube pre - the dreaded Alps Blue Velvet. Aside from not being granular enough, it also has a "missing" volume stop right where it is most noticeable and irritating. Based on the photo is there any room for a better replacement? It has to be motorized and controllable from my remote. |
