Triode announced on November 2nd that it will release the vacuum tube integrated amplifier "JUNONE 845S" from "JUNONE". Scheduled to be released in late November, the planned price is 968,000 yen.

It is an integrated amplifier that uses a large triode "845", and will be the flagship model of the integrated amplifier equipped with a triode, which is the company name of Triode. In addition to 845 x 2, the vacuum tubes are equipped with PSVANE WE300B x 2, 12AT7 x 2, and 12AX7 x 2. A newly developed 845 socket is used for the socket.

The circuit type is class A single, and the rated output is 22W + 22W (8Ω). The power supply unit, which consists of a large toroidal power transformer and a voltage doubler circuit, supplies a high voltage of about 1 kV and realizes a powerful sound in the entire band. The front panel is equipped with a bias meter, and the bias adjustment volume on the top of the chassis allows bias adjustment. In addition, the top of the chassis is equipped with a ham balancer volume for 845 and 300B, and the ham balance can be adjusted.
