The blackface Tremolux is a piggyback head with Normal and Vibrato channels and no reverb. Each channel has two inputs, volume, treble, bass and a bright switch. A 12AX7 runs an optical (lamp and LDR) vibrato on the Vibrato channel with speed, intensity and a pedal switch. A 12AT7 long-tail inverter drives a fixed-bias pair of 6L6GCs from a GZ34 rectifier, giving a firm, full blackface clean with a pulsing tremolo.
