Default Any external belt drive volume controllers w/remote

Someone told me that there is an external kit that one could add to a preamplifier to turn it into remote capable. I can not seem to find it anywhere. I prefer this solution to a adding a passive like a Creek obh or taking the preamplifier apart and using one of the Welbourne like devices.

Or has anyone tried the same thing where I had read about years ago someone took apart a kids remote controlled toy car and using the motor from it. Then placing it on the top of the preamplifier with a belt wrapping around the volume control.

Yeah, I saw that. I think his name was Rube Goldberg.

When I was a kid I taped strings to the light switch and window shade in my bedroom. I routed the strings so that one turned on the light and another turned it it off, etc. It was really cool!

Thank you for the help, but no.
It would a volume controller that would have a motor that sits on the top of my preamp and a belt that would come downwards to wrap around the existing volume knob.
I know it would be ugly but this way there would be no sound degradation due to replacing the existing volume control.

the link that jleaman posted would work. think about it, take off the knob from the motorized pot, install a pulley instead. put a belt from the pulley to the volume knob on your preamp. done.

edit:

forgot to mention, you can buy the kit without the attenuator. this way it would just be a motor, and allow you to do what you want.

Why don't you try that? You can get those cars at any garage sale for $1-5.

You could just use a control board for a motorized pot (like my Remote1), and substitute a small gear motor for the pot.

Best regards,
