Cyber300B Series Mono Block Tube Power Amplifier

Cyber300B

The Cyber300B is a very well thought out TJ300B single ended mono power amplifier.

Features:
- None negative feedback designto give the shortest signal path.
- Output transformer wound with special audio coating, and made from silicon steel laminations to resist saturation and provide linear frequency response.
- Rectifier 5AR4 tube in the power supply lets through all the magical tone of the 300B .
- Quiet torroidial power transformer; choke filtered power supply.
- Very powerful mono-triode 6C45pi direct drive the TJ/Full music 300B delivering 10 watt output power.
- Quality parts throughout and point to point wiring.
