Country of Origin:

The new A-36 inherits many of the outstanding design technology features developed for the higher-end models. It redefines the baseline for pure class A power amplifiers and represents the same unwavering attention to detail and dedication to sound quality for which Accuphase is justly famous.
In the output stage, power MOS-FETs renowned for their excellent frequency response, sonic performance, and superior reliability are used in a triple parallel configuration and driven in pure class A. This is sustained by the strong power supply featuring a massive transformer and two large 47,000μF filtering capacitors. Output power in each channel is rated for an impressive 150 watts into 1 ohm, 120 watts into 2 ohms, 60 watts into 4 ohms, and 30 watts into 8 ohms. Even speakers with ultralow impedance or drastic fluctuations in impedance curve can be driven reliably by this impressive amplifier.

In the output circuitry, MOS-FET switches are used in place of relays, to eliminate mechanical contacts and improve long-term reliability.

Warranty:

1-year manufacturer's warranty

Features:

  • Pure Class A operation delivers quality power: 30 watts x 2 into 8 ohms

  • 4-stage gain control

Video Review:

Power amplifier with “instrumentation amplifier” configuration

A balance amplifier is configured with the entire power amplifier including the signal input stage, realizing balanced transmission of the signal path from the input terminal to the output stage. For this reason, it has excellent performance such as the ability to remove noise generated in equipment and low distortion, and is resistant to changes in the surrounding environment, further improving stability and reliability as a power amplifier.

Equipped with a more advanced “MCS +” circuit
The power amplifier part is equipped with an "MCS +" circuit that is a further evolution of the Accuphase original MCS circuit that improves various characteristics by connecting the same circuit in parallel. Increased circuit stability and further noise reduction.

Power MOSFET, 3 parallel push-pull power unit guarantees 120W / 2Ω, 60W / 4Ω, 30W / 8Ω linear power per channel
Equipped with a large heat sink for heat generation by Class A operation. Even in a speaker system with a very low impedance of 1Ω, as a result of designing with a sufficient margin, 150 W / ch (limited to music signals) and a large output power were obtained.

Equipped with a “current feedback” amplifier circuit with excellent high-frequency phase characteristics and sound quality
A “current feedback” amplifier that feeds back the output signal in the form of current. Various characteristics can be greatly improved with a small amount of NFB, excellent dynamic characteristics such as rising, and natural energy response is possible in terms of sound quality.
