Product Details:
This EL84 electronic tube amplifier adopts AB1 push-pull amplifier circuit, with a gentle and full sound, transparent, delicate, smooth and clean The low distortion at the end of each frequency band makes the background quiet and very comfortable.
6F1/ECF80 composite transistor, with a five pole transistor as the input voltage amplifier, and a transistor inverting PK to drive EL84.
Using a 25H120 transformer with a 0.25mm thick "ultra-thin high-quality iron core, CNC winding machine precision winding, and tight, stable, and solid connections at each layer", it has low temperature rise and long service life.
The Japanese ALPS27 potentiometer has accurate positioning, good balance, and long lifespan.
Original ALPS band switch from Japan.
Gold-plated electronic tube holder.
Pure copper gold-plated RCA and terminal posts.
The chassis is made of 1.5mm thick iron plate, sprayed with powder and baked at high temperature, and then sprayed with high temperature gray paint.
The front panel is made of aluminum alloy CNC machining, with full chamfering process that does not scratch hands, and the surface is sandblasted and anodized.
Neat wiring, reasonable design, low communication interference.
Promote the use of composite tube acoustic Soviet 6H1N, replacing the model ECF80/PSVANE EL84.

Blue light is generated by the impact of electric ions on the plate, which excite the atoms in Nickel. When a high-speed electric ion of Barium Strontium strikes Nickel's atoms, it will also impact the electric ions in Nickel's atoms. At this time, Nickel's atoms lose their electric ions, resulting in a positive negative imbalance. They need to absorb the lost electric ions in nearby electrons to restore balance. When this situation occurs, blue light will be produced. This romantic blue light will not affect the audio and sound effects of the 300B.
