Single-Ended Triode Amplifier
Considered by many to be one of the best 300b amplifier made !!I am the second owner. It had the small mark on the back of the unit --see
Picks – when I bought it. Has no effect on the sound or construction quality of this heavy-duty heavy hitter. MD-300B is designed in pursuing of higher performance and new recognition of single ended amplifier by employing 300B tube well known for its original capability of reproducing natural sound with full of musicality. This amplifier reproduces a pure sound field and clear image which is only possible by single ended amplifier. Direct coupling circuitry between the first and 2nd stage without capacitor in order to keep maximum purity of sound quality. 6Y6 are employed in the second stage as triode operation. Power tube is driven by interstage transformer for ideal operation of 300B. Oriented-Highbee-core material are used in all transformers to ensure quality sound reproduction. Filaments of vacuum tubes are supplied by well-filtered DC current. In order to get clean plate current, MD-300B employs special Silicon-diode rectifiers which minimize noise. Anti-vibration construction is incorporated in MD-300B. Specs:
