Danelectro DS50 - Channel 1 preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The DS50 is a Danelectro valve combo with two channels, each with its own volume, treble and bass. A 6FQ7 drives and recovers a spring reverb, and a 12AX7 with an optical vibrato unit provides vibrato with speed and strength on a dual footswitch. A 6FQ7 phase inverter drives two fixed-bias 6L6GCs in push-pull from a solid-state rectifier, with a standby switch, into three 10-inch speakers for a loud, clean, bright sound.

• Wattage: 50W
• Channels: 2
• Preamp tubes: 3× 12AX7, 2× 6FQ7
• Power tubes: 2× 6L6GC
