Description:
CPI amplifier operating point selection in the characteristic curve is a straight line segment, nonlinear distortion relatively small, even harmonic content, but also the sound effects are very good, sound quality is moist and beautiful, sweet sounds quite "multi-string Qin sense of rhyme. But less efficient, less output power and higher speaker sensitivity requirements.
In order to solve the problem of single-tube Class A output power, with the difficult, the amplifier power tube parallel output, reducing the output impedance to enhance the driving force.
The machine adopts the old handmade scaffolding welding process manufacturing.
The first stage amplifier using the pentode 6J4P (or 6J8P) for amplification, pentode sounds gorgeous sounds, single-stage high gain, the machine this tube connected as triode form of enlarged, further reducing distortion, more delicate sound.
Second level to promote internal parallel twin dual triode 6N8P promote, 6N8P maximum anode dissipation power up to 6W about lower internal resistance in parallel impetus for better.
Rectifier with high-current rectifiers 5Z3P × 2 secondary rectification method, high-current amplification makes the CPI by better and more abundant supply.
