Volume Pot Upgraqde

I recently picked up a Sophia Electric Baby Tube Amp and would like to do some upgrades. The volume pot is is a 50K log pot.

Can anyone recommend a good replacement piece? Google isn't quite finding me anything...

It's a pretty tight fit, so any parts would need to be small enough to fit in the chassis.

How about an external switch box like the Goldpoint SW4 ($352) so you don't have to drill into the preamp.

Wish that I had these kind of options when I did a project like this years ago.

Instead of coupling capacitors, consider a Jensen or Lundahl 1:1 line level output transformer.

Just looked up that Bent Audio has 50K attenuator modules and the small PRM-1 module that takes the place of the volume knob, if you don't mind buttons. Nice thing is that it adds remote. Also has power supply options.

Consider a shunt volume control with a 50K TX2575 series resistor and a Silonex variable light-dependent resistor in the shunt position. This is explicated in the Lightspeed DIYaudio thread. This will surpass a convention series attentuator.
