this is the Upgraded version of the shengya A-238, Now the parts have upgraded
Feature:
The pre-amplification part adopts imported ECC83 tube common cathode type amplifying circuit, and imported ECC82 tube acts as SRPP for driving amplification;
Adopt hybrid precision high-voltage stabilized power supply of electron tube and transistor, the voltage stability is extremely high; the power amplifier is composed of Japan Toshiba high-power transistor to form a 0dB current amplifier circuit;
The tube circuit cross-connect and de-cross-connect capacitors are German WIMA brand MKP series high-end audio special capacitors; the filter capacitor used in the transistor power amplifier power supply is Japan ELNA brand FORAUDIO series 10000uf / 50v specifications;
The volume control uses the electronic volume control chip CS3310 manufactured by American Crystal Corporation;
The ring-shaped high-power transformer with shielding box is placed in the machine, and the entire transformer is filled with epoxy resin, which effectively reduces the vibration and noise generated by the transformer during operation;
The AC power socket uses gold-plated products of the Japanese Furukawa brand
Two-channel independent use of dedicated audio filter capacitors and rectifiers, with a total capacity of up to 120,000 microfarads, 32 high-power transistors composed of 100W (8Ω) pure class A output power per channel;
The speaker terminal is selected from the German WBT brand, and the signal input LINE1 is also selected from the German WBT brand;
Another function of this machine is that it can be used as an independent post-stage power amplifier. LINE5 high-level signal input terminal can be used to connect other pre-stages as a post-stage power amplifier;
This machine introduces CPU full-function control and data information screen display mode; set up infrared full-function remote control system.
