In original schematic, there is no filter choke, it bring much hum noise as using with high sensitive speaker. This amplifier use filter choke to make the noise go under 1mV, It is very good number when 300B heater is AC direct heat. You can even lower the noise if using DC heater but to keep the sound of amplifier closest to original sound, I keep original schematic using AC heater.
Wiring use 50s year original Western Electric wire.
Output transformer use Western Electric transformer core and rewiring.
