Product features:

●Twenty-two watts per channel, Single Ended Triode design, Pure Class A Integrated

Stereo Amplifier with 845 output power tubes.

●All tube Integrated with 12AX7 input tubes for voltage amplification, 6P3P driver tubes,

5AR4 rectifier tubes and 845 output tubes. Driver tubes 6P3P can also be replaced by

different kinds of driver tubes and you can select which tubes you prefer judging by

different sounds.

●4 pairs of inputs and speaker terminals for 4, 8 and 16 ohm speakers are located on the

back panel.

●User bias control has been used for bias adjustment and one meter has been added to

the front plate to allow you to monitor bias with ease.

●External Hum Balance adjustment for sound adjustment.

●Specially designed EI transformers for power supply and two EI output transformers

with wide bandwidth are applied.

●JapaneseALPS volume potentiometer, German N-cap coupling capacitors etc Audio

grade components have been applied.

●Standard with remote control.

●Hand made construction with the finest point-to-point wiring.

●Soft Start and time-delay circuit. (30 seconds).
