Panaramic 1220 - Channel 1 preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Panaramic 1220 is a 1960 tube instrument amp from Estey Electronics of Torrance, California. Two channels, each with A/B inputs, a 12AX7 stage and its own Treble, Bass and Volume, add a Mellow/Normal switch on channel 1 and Normal/Bright on channel 2, plus a stereo input. Its patent-applied vibrato uses a 12AX7 oscillator with Rate and Intensity and two 6CG7 phase-shift stages, footswitchable, ahead of a 12AX7 inverter, two 6L6s and a 5U4GB rectifier.
