Marshall Popular 1930 - Channel 1 preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Model 1930 Popular is a small 10-watt Marshall valve combo with tremolo. Two pairs of inputs, each with its own volume and the first with a tone control, feed one half of an ECC83, while the other half runs the tremolo oscillator with speed and intensity. The triode sections of two ECL86 triode-pentodes form the phase splitter, and their pentode sections run push-pull for about 10 watts into the speaker.
