Product Details:
Adopt Beijing 6N2 electronic tube and Beijing FU32 vacuum tube, parallel Class A amplifier circuit, and output transformer output.
The core output transformer is made of Z11 0.35MM 66*19 silicon wafer with special process winding, and the power supply is made of H 14 360 0.5 annealed silicon wafer.
One RCA audio source input, perfect earphone protection circuit, output transformer no-load protection.
Use all AC filaments to light up, use 102DB earphones to try it out, you can't hear a little hum noise, it's very quiet.
Output 4W+4W power amplification, and push the speaker to require a two-way speaker with an impedance of 4~8Ω, a sensitivity of 6.5 inches above 90db, and headphones 19-600 ohms (about 1w)
The volume potentiometer adopts Taiwan-funded A100k fully sealed potentiometer to ensure clear positioning and left-right balance.
Using metal film resistors and imported electrolytic capacitors with an accuracy of up to 1%.
It adopts 0.8mm brushed surface stainless steel chassis structure.
