Danelectro Twin 15 - Channel 1 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 1961 Danelectro Twin 15 (Model 217) is a two-channel valve amp with strong and normal inputs. A 12AX7 gives each channel its own bass, treble and volume, a second 12AX7 adds gain, and a 6FQ7 phase inverter drives four cathode-biased 6L6GCs as two pairs, each with its own output transformer and 15-inch speaker. A 6AU6 oscillator gives vibrato with speed and strength on a footswitch, from a 5U4 rectifier with a choke and standby.
