Features:

High signal-to-noise ratio, no bottom noise, strong gall smell, power on, no noise, turn up the volume still the same

1、 Component selection

All parts of this product are original and have a long service life,

◆ CLRC is used for high voltage power supply. The rectifier adopts 5Z4P to provide sufficient current margin,

◆ Output coupling capacitor adopts Hong Kong RICA tin film 4700P+Hong Kong TE

◆ Two domestic Changsha Shuguang 6J8P J-pole electronic tubes (717A and 6SJ7 can be directly replaced, or EF50 or CV1091 imported cartridges can be used through the conversion seat of our store, with obvious effect improvement),one 5Z4P rectifier tube (5U4G, 5U4C, 5AR4, 5Z3P, 5U3C, 274B, GZ34 can be directly replaced).

◆ It is applicable to any subsequent power amplifier.
