SUN AUDIO SV-300BTE

Used. In good condition. Shows some signs of wear. Supplied with original packaging.

The Sun Audio SV-300BTE are monaural tube power amplifiers designed and manufactured by the Japanese company Sun Audio. The Single-Ended configuration uses a 300B tube as the main active device in the amplification stage, with one unit dedicated to each channel.

The design incorporates transformers specially manufactured by Tamura Corporation. The transformers are equipped with pre-wired leads, making assembly easier; the interstage transformer is the exception, as it follows a specific configuration.

The entire circuit uses point-to-point wiring, without the use of printed circuit boards. This approach allows the connections to be made directly between the components and the connections mounted on the chassis, following a traditional construction method for tube electronics.
