Step Attenuator

Hi guys!

I need a good stepper attenuator.
Preferably more than 23 positions, with non-metallic resistors (better carbon or wirewound).
I have just tried a chinese audiometric.com but it broke immediately.
Not Elma unless it's already mounted, even only 23 positions. And not DACT.
Please if possibile better ladder type 50KOhm stereo logarithmic.

Thanks.
 
Micheal Percy stocks a 45 position 2 deck Shallco switch. The Shallco part is physically huge.

Wirewound resistors are metallic. Carbon film parts require hand matching. Non-metallic, non-inductive, and 1% tolerance are what you get with Caddock resistors.

Perhaps a good off the shelf volume control, with an "infinite" number of positions, is what's needed. PEC hot molded carbon parts match that description and they are reasonably priced. ;)
