power dampening

[phsyconoodler]

I did a power dampening mod on an amp a few years ago but I can't remember how I did it.(old age setting in)
  I think I just out a 50k pot between the PI cathode resistor and the tube.
 I liked the effect on the amp for lowering the volume.It did alter the tone but I never used it for really low volumes,just a throttle sort of on stage.
  Anyone have any info on this? Memory and my crashed hard drive have failed me.

Look at page three. Just replace the switch and resistors with a 50K pot wired as a variable resistor.

Thanks Sluckey! You're the best!

Next question:will it work on a cathodyne PI ? I'm thinking it should.But.....

I'm going to try this on my bassman 50

It will work, don't know if the result tone will be of your taste (that is a personal question), but it will work
