The sound like high end 300B amplifier

Pursuing the sound of well-established "45" tube to the limit

Description
Adopted balloon type 245,345 tubes make its sound very natural, clear, warm, comfortable to listen. The rectifier tube is also balloon type 280,380 tube as well.

A-08S Balloon produces not so much output power though, the quality of sound could be matched with high-end 300B amplifier.
A-08S Balloon is designed for pulling out the best performance combination with high efficiency speaker system.

All power supply transformers, output transformers, chalk coils adopt cut core transformers which use only highend High B typemodel.
Each transformer covered with resin to keep the performance and the quality. Especially the output transformeruses 100 micron thickness core material is wrapped with the insulation paper of Teflon. Also refined trans wiringmethod for A-08S then improved the frequency characteristic.
Also, mainly adopting the polypropylene capacitor. The responsiveness to the signal of the palace nature of the ratio sob this polypropylene capacitor excels in a usual chemical capacitor and also even the distortion rate of capacitor oneself excellent very much.
A-08S is supplied Yamamoto Sound original capacitors for the coupling condenser and the input capacitor of power supply that quiet affects sound quality. This Yamamoto original capacitor is epoxy resined into the ebony wooden case or bakelite case. It has accomplished sound quality improvement by preventing the vibration of the elements.

The tube socket is famous Teflon made. High quality Input terminal of external conducter adopts solid chromium copper, internal pin adopts solid Adjacent copper and insulated material is Teflon made. Output speaker terminal is Gold plated pure copper with Teflon insulator. The terminal accepts 8mm extra thickness speaker cable.

Cabinet base is solid high quality African ebony that Yamamoto Sound is providing it as setting bases.

It is able to monitor the current of the output tube and grasp the condition of the vacuum tube.
