Description

Ultra-wide bandwidth output toroidal transformer with Cathode Feedback CFB windings introduces benefits of toroidal cores to tube output. Cathode Feedback CFB winding allow You to take well know advantages of this kind of circuits such as larger damping factor an much better controlled, extremely quick, tight and powerfull bass response.
Cathode Feedback also minimizes THD and intermodulation distortions and makes total bandwidth ultra-wide without using overal negative feedback from output to input of Your amp. All of it makes Your sound amazing, detailed and spacious.
