Core line: refer to the high-end model SF200 of the British Sedun amplifier, the original price is about 25,000RMB;
The input uses 2 twin FETs,  NE5534.
Magnification: 24.4 times; the original machine adopts passive preamp mode, potentiometer 50K;
Output power: 100w/8 ohms & 200w/4 ohms;
Output large tube: Sanken 2SC2922/A1216, the thrust is equivalent to 3 pairs of common Power transistor in parallel. 230v/17A/200W/60MHZ.
Assembeld board sales: All assembeld boards pass the midpoint test, noise test, maximum output waveform test, etc.
Noise level: 0.2mV; input uses twin field effect tube, the noise is extremely low;
Midpoint voltage: 1mV; DC servo line, which makes the high and low sounds more transparent;
Class A current: When the temperature of the transformer and radiator is allowed, try to increase the quiescent current as much as possible. Feel the charm of Class A power amplifier (warm, transparent.


NOTE: This is a MONO assembeld and tested board, If you want to establish a stereo, you need to buy 2 PCS.
