Junone 845S is a single-ended Class A integrated amplifier with an output power of 22 watts/channel into 8 ohms.

A flagship model with a triode, it achieves a power rating of 22W + 22W with a single-circuit Class A configuration that lets you enjoy the powerful sound of the 845 vacuum tube. The power supply, consisting of a large toroidal transformer and a voltage doubler circuit, provides a high voltage of around 1 kV and produces powerful sound in all bands.

In addition to the 845 x 2, PSVANE WE300B x 2, 12AT7 x 2, 12AX7 x 2. With the new 845 socket, the 845 vacuum tube is used at a high voltage of around 1 kV. It is a high-precision electrical socket designed for frequent withdrawals and long-term use.

The front panel is fitted with a polarisation indicator, and the polarisation adjustment volume on the top of the case makes it easy to adjust the polarisation. In addition, the top of the chassis is equipped with a Ham balance volume for the 845 and 300B.

Equipped with a speaker output. The input connection comprises 4 lines and 1 MAIN IN input, which can be used as a power amplifier by bypassing the preamplifier stage. Input sensitivity/impedance is 220 mV/100 kΩ for the line input and 1500 mV/10 kΩ for the MAIN IN.

Frequency range is 25Hz to 36kHz. The SN ratio is 85 dB. Power consumption is 330W. The external dimensions are 430 x 410 x 277 mm (width x depth x height).

Weight: 45 kg. The power cord is supplied as standard with TR-PS2 (high quality power cord using oxygen-free copper with immersion moulding).

A machined aluminium remote control for volume and mute controls is also included.
