Hagstrom 310 - Channel 2 preset

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

The Model 310 is a small valve amplifier from Hagstrom of Alvdalen, Sweden. Four inputs feed the two halves of an ECC83, one per channel, each with its own level control, followed by a tone network. Half of a second ECC83 runs a phase-shift tremolo with a speed control and footswitch. The output is a single ECLL800 dual pentode working as a cathode-biased push-pull pair into a 16-ohm speaker, with a solid-state rectifier, for roughly 10 watts.
