To the cleverest out there--Time for Remote!

I wish the cleverest folks out there would devise a device (maybe an external one) that would mechanically turn the volume knob or stick behind the knob on the TU 8600.

I have ideas but I'm not that mechanically inclined (I'm only handy).

I've seen people take a cheap preamp and place it under their volume knob and have it rotate the unit without a remote by turning a rubber band. That's a start.

Essentially I am asking, hey, we have external power supplies, why not invent an external remote volume device that attaches to the front of the amp?

Now, if one could be fashioned internally--all the better (maybe not sonically)--yet there's no room in the Elekit to do anything internally.

It's 2020--I don't care if it's Elekit or AudioNote or some boutique amp.... I need a remote!!
 
Perhaps a small box full of electronics which is installed into the signal chain right before the amplifier. The wireless remote adjusts the gain/attenuation of this small box, whose output feeds the Elekit amplifier. Set the Elekit's volume control to 75% rotation, fix it in position using chewing gum or silicone bathtub caulk, and let New Box Thingy do the rest.
