Chassis finished (8R/4R impedance switch with parallel output sockets on back. Humdinger pot with c-head knob, Mains and HT fuses)
Chassis finished by

Reused old front panel ('Slope' switch is now a mid-hump/scoop selector, 'Boost' is now a raw/tone stack lift. James tone stack, Normal and Hot inputs - can also run as stereo inputs)

Schematic (Cross between a 1-channel tweed pro and a goosed up t-bolt). Can run either 5AR4 or 5U4G with two (cathode-biased) 5881s or 6L6s, or a 5Y3GT with two 6V6s (if the speakers are switched 'up a notch' on the OT).

Humpty all put together again
Front view (same as before) - note the speaker hole shadow in the grille from the old baffle - tried cleaning this away with dry-cleaning spray but its permanently relic'd.
