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. 😉

Why do you need more than 23 positions? I used 12 for a while when I made my own, since they're easily available. And since I built it I could chose the values in the range I listened most to.

Anything wrong with this Valab one? It's a ladder type (2 resistors at a time). They also have a SMD one with Vishays, but don't say if it's ladder. Anyone tried these two?

Thanks to all!
I have found interesting the 41 position Shalko but it's not clear what type of resistor they use. I hope not metallic. After the 46 positions square at 179 with Cadoc resistors seems very good, maybe the best.
What do you think? Who is the best?
Bye!

SMD 1% non inductive metal film
Curious why not Dact?.
Really I don't like SMD resistors, and I have heard rumors that Dact is a bit fragile.
I have decided to DIY an attenuator with an ELMA series type with carbon resistors.
Please I need a program to calculate the values of the resistors for a 50K.
Thanks!

Hi,
In Italy there is Palazzo (in Torino) who made a good 23 position switch.
The best solution on resistor, for me, are Holco h8.
For the value of 50k resistor, send me an email
Ciao

hi guys, no one of you kind people can indicate toi me a program to calcolate the value of the resistoirs for a stereo 590 kohm series tyoe?
cheers and thanks in advance

I would use Microsoft Excel.
There is an Excel program available here:
DACT Attenuation Curve Calculator
That appears to do what you want.
