Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Silvertone 1300 is a 1950 Sears tube combo with two instrument inputs on one volume and a third input for an instrument or microphone with its own volume and 6SL7 preamp stage. A second 6SL7 provides gain and a paraphase phase inverter driving two cathode-biased 6V6GTs push-pull, with a single tone control, a 5Y3GT rectifier and a field-coil speaker.
