Hagstrom 614 - Channel 1 preset

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

The Hagstrom 614 is a Swedish valve amplifier, drawn in 1960 as a separate preamp and power amp. Kanal 1 has two mic inputs and a tape (Band) input on an EF86 pentode; Kanal 2/3 has two more mic inputs on half an ECC83; each channel has its own tone (Ton) and volume (Volym). The other ECC83 half runs a tremolo with a footswitch. The power amp uses an EF86 and an ECC83 to drive a push-pull pair of EL84s, on an EZ81 rectifier.
