Headphones amplifiers
Master 300b amplifier is single ended DHT integrated amplifier capable to drive loudspeakers and headphones from 50Ohms to 600Ohms. Input tube, for both channels, is 6SN7 as voltage amplifier, driver tubes per channel are 300b and output tubes are 300b. Why 300b drives 300b? Sound advantage and reduction of distortion.
