Carlsbro 60 TC Twin - Treble preset
Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.
The 60 TC Twin is a 60-watt Carlsbro valve combo with Bass and Treble channels. Each channel has its own pair of inputs, an ECC83 triode, a passive treble and bass network, a volume control and a second ECC83 triode; the Treble channel adds a Top Cut control. An ECC83 long-tail phase inverter with negative feedback drives a pair of fixed-bias EL34s at about 450 V from a silicon rectifier, with 3.75, 7.5 and 15 ohm taps.
