Divided By 13 FTR 37 - Channel 1 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The FTR 37 is a boutique two-channel, 37-watt amp from Divided by 13. Channel 1 runs a 5879 pentode into a six-position rotary tone switch and its own volume for a bright, glassy voice; channel 2 is a 12AX7 channel with treble, bass, volume and a pull switch, feeding a 12AT7-driven spring reverb. A 12AX7 long-tailed-pair inverter drives four cathode-biased 6V6s with a half-power switch and a GZ34 rectifier.
