Here's a shot of the inside of the left side of the cabinet, below the LV supplies. At the top can be seen the filament transformer for the Final bias supply. The rectangular black object above the variable autotransformer is one of the main power switches. The relay below the filter board is the plate overload relay. The modulator filament trnasformers can be seen behind the metal plate with the four relays. These relays bypass the tune-up/low power resistive elements, key the HV transformer primaries, and also key the PA screen voltage.
