● The first stage of amplification uses the hexapole 6J4P (or 6J8P) for amplification. The chromaticity of the pentode is gorgeous, and the single-stage gain is high. The unit is connected to the triode to amplify the lens, further reducing the distortion and making the tone more delicate.
● The second stage promotes the use of twin-stage three-stage tube 6N8P internal parallel push. The maximum anode dissipated power of 6N8P can reach about 6W, and the internal resistance is lower after parallel connection, and the driving force is better.
●The rectification adopts the high-current rectifier T-type hook filament 5Z3PA×2 secondary rectification method, which makes the high-current supply of Class A amplification better and more abundant.
