!!!WARNING!!!

The voltages found in this circuit can be lethal, build at your own risk!!!

The output stage is a SE 300B triode and the maximum power output is about 8 Watts per channel.

A pair of reasonably sensitive (>91 dB/1W/1m) loudspeakers will be required with this 300B SET amplifier.

The circuit design is old school, no negative feedback of any kind, wiring is standard point-to-point.
