Believe or not - just 30 minutes ago is was working on the same problem and I found a solution. I have a similar stepped attenuator and was thinking for hours about how to drive it remotely. The crunchpoint is the latch: To turn the axis and click the latch into place it needs some torque, more than the tiny motors of remote driven potentiometers can deliver. So I dismantled my attenuator, and took off the latch (two rebound springs, mounted crosswise on the axis, each pressing a metall pellet into notches). So there is no more clicking, the torque needed is very small.

On stock I have a reasonably priced remote control set, found it here:

I dismantled the potentiometer and now I use the motor and gear to drive my attenuator. The axis of the gear is very thin, so I had to make an adaptor to make it fit on the attenuator´s axis.

The gear has a friction clutch, so the motor will not be blocking when reaching the attenuator end position.

Hope this helps ...

Thankyou very much, simple and effective solution: in fact who cares about click steps if the attenuator works correctly. Do you check problems in attenuation?

No problems at all, it just works fine. Due to the fact that stepped attenuators use "make before break" type switches (everything else would cause nasty thumps when switching between the steps) there can´t be any drawback.

Great! Thanks a lot! I will do the same.

Shipping to Europe will cost more than the kit, I guess. And then the customs ...

Thanks anyway.

Shipping would be less than 10USD and there should be no custom charges if sent as a low value gift. Just trying to help!
