composed of domestic junction field effect tube 3D J6F and domestic 6P3P

the input stage for low-power amplifiers , both the sound quality and dynamic range are better than amplifiers
using 6N1 and other tubes .     Even if an ordinary output transformer is used, the sound quality is not comparable to that of ordinary large-screen color TV speakers. Its input can be directly connected to CD or VCD. SV CD . CVD output.
