Commentary

Bulb-type integrated amplifier.

It uses a construction that looks like a One box with separate amplifiers. Four sections of right channel power, left channel power, pre-heater circuit are equipped with independent power transformers, and a total of 15 power supplies are configured.

The S. T. A. R. circuit (Signal Transit For Accurate Response Cercuit) is used as a result of a thorough review of the artwork of the circuit, focusing on the occurrence of current interference in the common part of the circuit.
Each line is directly connected from the reference point to the signal path and power supply line of each block to form an independent loop, eliminating the stagnation of current that interferes between blocks.

Each amplifier stage is equipped with a regulator circuit, and through a thorough review from the basics, the purity of sound quality is realized.
As for the heater circuit, each stage is stabilized to prevent thermal modulation and signal from the heater circuit, and to extract the sound of the vacuum tube.
