Introduction:
A amplifier operating point selection in a straight line segment of the characteristic curve, nonlinear distortion is relatively small, even-order harmonic content is high, very good sound effects, sound quality is beautiful moist, sweet and pleasant, quite "multi-harp" rhyme sense. But less efficient, higher output power is small, the speaker sensitivity.In order to solve the problem of single-tube Class A output power with the amplifier power tubes in parallel output, reducing the output impedance, and enhance the driving force.This machine adopts the old handmade scaffolding welding process.For the first stage amplification with five very the tube 6J4P (or 6J8P) amplification, pentode tone sounds gorgeous, single-stage high gain, the machine this pipe into the transistor forms of amplification, further reducing distortion, making the sound more delicate.
The second level to promote the adoption of twin pairs three internal shunt tube 6N8P promote, the 6N8P maximum anode dissipation power up to 6W about parallel internal resistance of a lower driving force for better.
Rectifier high current rectifier 5Z3P × 2 secondary rectifier, making the supply of high-current amplification by the CPI (A) through better, more abundant.
