Make R1 100k. The Bass pot is apparently reverse log, if you cannot locate one connect it to a standard log with reversed leads. If you do not need the fx loop you can eliminate C6 & R6 and go straight from the vol pot to C11 coupling cap.

MJ Harnish built one using an EF86 instead of the 6SH7, and has component values for that. I built one using a 6AU6 instead of the 6SH7, and have values for that if your interested.

scott c	If you do not need the fx loop you can eliminate C6 & R6 and go straight from the vol pot to C11 coupling cap. what about r4? do i leave it in? does it go to ground or in series with c11?

hasserl	I believe it is difficult getting good non-microphonic 6SH7's, and is why Matchless also went to EF86. Though I believe these also have microphonic problems and is why Vox moved away from them. Though several guys here have used them succesfully in other builds, and love the sound. R4 stays, in series w/ c11.
