The Rosac Nu-Fuzz is an Ed Sanner design, of Mosrite fame, so there’s an element of Fuzzrite happening with the Nu-Fuzz.  The Nu-Fuzz was released after the Fuzzrite.

ROSAC NU-FUZZ – POINT TO POINT LAYOUT

There’s some odd resistor values used, just try the nearest match that you can find, and maybe experiment a little.  You could increase the 10uf cap to something much larger and add some filtering via the usual 100ohm / 100uf RC filter combo.  Like anything of this vintage, batteries were the go to power supply.
