Mono block tube power amps (TJ300B single ended, 10 W)/pair

The Consonance Cyber 300B 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.

The output transformer quality is always of paramount concern especially with 300B amps.

The Consonance Cyber 300B uses selected silicon steel in c-cut form. We winds the primary and secondary coils with a special technique to achieve close coupling.

Traditional paper and varnish is used for coil insulation and traditional damp proofing techniques are also applied.

The transformers are visually impressive but even more impressive is their ability to a deliver smooth solid and musical deep-bass.

A secret revealed how to increase dynamics and liquidity. Many have wondered why the output transformer sound so good considering their non-exotic cores. The answer is that the laminations are mixed with vintage military surplus transformer laminations.

These are from transformers that have seen years of service. As vintage-buffs know much of the good sound has to do with long-term conditioning of the metals and wire. Mechanical stresses relax over time enhancing magnetic performance.
