Commentary.

An integrated amplifier that improves the characteristics of the equalizer stage by using the ICL method and a 2-stage direct connection 2-power supply configuration.

The first stage FET differential amplification ICL system is adopted as an equalizer stage, and the phase characteristic and the transient characteristic are improved.

Moreover, the circuit configuration has a two-stage direct connection ± 2 power supply configuration.

The all-stage direct connection + pure complementary OCL circuit of the first stage differential amplification is adopted as a power amplifier part, and the load circuit of a class A amplification is made a constant current, and the stability is improved.

The large power transformer with good regulation and two 10,000F electrolytic capacitors are adopted as a power-source part.

The double protection circuit by ASO detection type limiter and relay is carried in the protection circuit.

The ± 2 power supply system which used the low noise operational amplifier is adopted as an equalizer amplifier part.

The CR element is a low distortion tone control which is included in the NFB circuit, and in the tone defeet position, the CR element of the NFB circuit is disengaged, and it becomes a buffer amplifier with excellent DC stability and phase characteristics.

The first stage FET differential amplification ICL equalizer stage, selection NFB type tone control, all stages direct connection pure complementary OCL power amplifier, and ± 2 power supply system are adopted as all stages, and the circuit is stabilized.

The left and right independent power meters that can read the output directly are carried.

The W direct reading type can read from 0.01W to 60W, and the meter range can be switched between 60W and 3W.

The subsonic filter and the -20dB attenuator are carried.

The detent volume of 41 clicks is adopted as a volume.

There was a wood case with Brazilian rose finish as an option.
