Aside from Alps RK-50, are there any quality quad potentiometers? I'm just curious if there are any others out there.

there is also the Penny and Giles pot. but some say that the cheap $4 quad Alps carbon pot is the best if you can find one with decent tracking.

this one:

carbon pots sound special

... but go ahead. buy that quad Alps RK50 and tell us how it is like. they are hard to find, but I know headroom stocks them.

Alps RK-27 blue velvet quad version. Never seen it advertised on DIY sites, but it definitely exists as HeadRoom use it as the stock pot in their Desktop and Home Balanced amps...

Not buying any - just curious about quad pots. Besides that thing costs as much as some amps.

And don't forget the Quad TKD pot. It's about $200.

It's good to know the quad Alps RK27 exists. It's not in the Alps datasheet
