This is a bit ugly, I took an existing layout and edited it ... the sag resistor is still too large it should be a 120 ohm or so ... also the last dropping resistor value will depend on the power supply voltage it could be as low as 15k and maybe up to over 27k ...

First is the layout with a MOSFET source follower ... second is the layout in 'stock' form without the source follower.

One common mod is to remove the 500pf cap over the 470k resistor just prior to the gain control, or replace the 470k with a 68k for a bit more gain and a thicker tone.

SuperliteIIb - layout with MOSFET source follower

I haven't built from this layout yet, I've built the circuit with a Superlite_II pcb to document the pcb build. I added the MOSFET source follower to my amp as I wanted to try it. It's a nice amp, good cleans, typical 18 Watt power tube crunch and more preamp gain.
