I can think of many SS/hybrid manufacturers that avoid Blue Velvet pots. But when it comes to pure valves I can only think of BAT and Aric Audio that do the same. I am sure there are more, but it seems tube gear falls into the ALPS trap more easily. Any help on other options (pre or integrated)?
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.
