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.

After reading this post, i checked the motorized volume pot on my LTA MZ2 and it appears to be the RK50A. And it's well under $10k.

I was going by the label on top that shows

50KA X 2

I this to indicate some stereo version of the RK50 but I may be completely mistaken. One can hope.

Yeah, it's a $16 pot available everywhere, probably on par with the 27. But the RK50 is about 100x the price, $1500 or so. So there's another reason for an upgrade. Oh well.
