I didn't do the options jim p posted figuring I wanted a base line sound to compare before making the mods. I have a couple of questions that i hope jim p, or anyone might be able to answer.
What does "maximum signal at the grid of the second tirode" mentioned in the options to the mod do in terms of volume, overdrive/distortion, etc?
I use this amp as my living room practice amp so generally the more overdrive/distortion at lower volume the better (within reason). I've wondered if adding another pot to control volume between the second tirode and the EL84 would act as a master volume and allow me to get more distortion at lower volume via preamp overdrive, although preamp overdrive is generally not as smooth as power amp overdrive.
