National De Luxe - Instrument preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A Valco-built National combo with a mic input and an instrument input, each with its own volume, and a shared tone control. A 6SC7 preamp and 6SL7 phase inverter drive a pair of 6L6Gs in push-pull, with a 5U4 rectifier. Its all-octal early Valco circuit gives it a raw, loose breakup.
