Class A single end integrated power amplifier

There is no doubt that this T3B-6 model is the newest and best generation of BEZ integrated power amplifier.

It adopts American old fashion tube 3D6 which can improve the original design to get a new high level of sounds.

The circuit adopts alternating current(AC) to supply the filament of 300B. This design can max the power gain by 300B tube. It makes sure you get enough power for your speakers, meanwhile, lowest the hum level, guarantee the sounds quality.

2A3B is also available, only you need to do is to turn the AC switch from 5V(for 300B) to 2.5V(for 2A3B), and you can get another choice to enjoy your music. Hum level 2A3B is less than 2 mV when you are using 8Ω output, you can hardly detect any noise when your ears close to the speakers.

You’ll be astounded at the improvement in sound quality, dynamic range, meticulous transparency, completely demonstrate its high performance and analytical ability.

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

The sound of the T3B-6 could also be better than amps which cost you 2-3 times from other factories.

Sounds is always our first target.
