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.
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. |
@bolong This VC should fit quite nicely and give you a substantial improvement in sound quality. https://www.hificollective.co.uk/catalog/potentiometer/100k-tkd-2dp-2511-mc.html TKD is a little hard to get in the US. Michael Percy is normally the best source, but I'm not sure whether he stocks motorized versions. Google him and reach out to him. Good luck! |
