I took a look at this for markleton. For anyone not looking at the other (OLC Shredmeister) thread, it turned out that a bunch of the caps supplied were ten times the value they should be.
In the absence of a metal box, cardboard will do..

Trim pots adjusted to give around 4.5v on the drain (D) of the FET

All those caps showing u22 instead of 223...

Critical ones in the tone stack replaced by 223 to get bass control working

I'm not sure about this design.

The trim pots that adjust the drain current and voltage also affect the gain, so not that much like the Soldano valve amp it's meant to be based on.
