Vacuum tube used 6DJ8 Audio Tube : 5 pieces and 6CA4 Rectifier Tube : 1

From their sales info: In this Counterpoint amplifier, we pay attention to the merits of voltage-controlled amplification which is a characteristic of vacuum tubes. By using MOS-FET as the same voltage-controlled device, large output can be efficiently extracted without losing the concept of the tube ball-type voltage-controlled amplification.

The SA-22 uses a twin triode 6DJ8 with low internal resistance and excellent linearity for the first and second voltage amplification stages and driver stages. The driver stage uses a cathode follower circuit with a constant current load to achieve further linearity and low distortion. MOS-FET is used for the output stage. By removing the output stage from the NFB loop, there is no need to worry about oscillation caused by inductance of the speaker or network under any load.

The power supply section employs a large power transformer of 1 kVA in an independent configuration on the left and right sides. The power is rectified by 6CA4 and supplied to each section through a transistor-type ripple filter. DC ignition is used for the heater circuit. BTL connection is possible by switching the switch on the printed circuit board, and the highly reliable 6DJ8 phase inverter is used.

This is on display and ready to be auditioned in our showroom.
