T4D-5 300B

Class A single end monoblock valve power amplifier

ThisT4D-5 300B is one of the best models of BEZ power amplifiers.

If you are a 300B lover and seeking to more power with wonderful sounds, then this monoblock amp cannot be passed by. It comes up with PSVANE 300B which could be the best tube from China.

The circuit adopts direct current(DC) to supply the filament of 300B. This design can minimum the hum level of 300B tube. This model which was designed as a monoblock makes sure you get enough power for your speakers, meanwhile, lowest the hum level, guarantee the sounds quality.

Output and power transformers used are made by our BEZ. They are designed for audio use particularly.

There are two groups of RAC input sockets seperately located in the front and the back which help you to arrange your amps more convenient.

Opened, detailed, sweet, warm..., you can get very pleasant sound in this model, it is suit for Hi Fi listeners.

All point to point hand wiring feature always has better sounds than those amps using PCB.
