Best way to add remote volume control to tube pre.

A friend of mine came up with this one. No degradation to the sound whatsoever.

He disassembled a remote control toy car or something, ran a belt or big O-ring around the volume knob and a wheel. He then use the remote control (for the toy car) to change volume. It works and no degradation to the sound. I would think you would want to find one that has a quiet motor, and allows you to be able to run at slow speed for fine adjustment of the volume.

If the pre has or can be refitted with a high-quality stepped attenuator, Bent Audio makes a nice motor-drive/infrared remote kit.

Thanks for the suggestions. It does have a stepped attenuator.
I need to think about this.

Placette all the way.

OK, thanks. Has anyone out there used the Placette in front of a preamp? Thanks.
