300B single vacuum tube stereo integrated amplifier that draws out the music’s reality and the artist’s passion

Product Outline and Concept

In the world of audio amplifiers, there is a wide range of types, from semiconductor amplifiers to

vacuum tube amplifiers, each of which has its own advantages and can be enjoyed as a hobby for

audios.
In particular, there are several vacuum tube power amplifiers, which are known for their sound

quality and are called "famous valves."
Among them, by using the 300B vacuum tube which is considered to be the highest rank, in 2017,
Phasemation developed the MA-1500 as the monaural power amplifier that powerfully drives the
transformer coupling with a single output.

In 2024, in order to express the significance of the MA-1500 to more people, we developed a new

product, the SA-1500 stereo integrated amplifier preserving a single 300B single-tube operation and

8W output power.

Features

1. 300B output tube driven best with 6SN7

Letting the 300B output tube to be a self-biased single pure class-A operation, 6SN7 is used in a

2-stages(1st & 2nd stage) amplification circuit.
To exert the original quality of the 300B with the simplest operation, the speakers are driven with firm stability.

2. Non-feedback amplifier configuration with triode tubes in all stages

The amplifier circuit is composed of an 6SN7 2 stage amplifier +300B triode tube in all stages to

achieve the dynamic and expressive unique music playing capability that is only possible with a

non-feedback circuit.

3. Adoption of the output transformer made by Lundahl, Sweden

The Lundahl output transformers were selected to best match this model’s composition and

prepared a common terminal that can best drive the 4 to 8 ohm speaker.

4. Configuration of an L/R independent power choke transformer

Power is supplied to left and right channels from independent power supply choke coils, allowing it

to eliminate mutual interference between the left and right channels and clearly amplifies the

signals from low to high power signals.

5. Complete design of low noises

For the high-voltage power supply, we adopted a rectification circuit with a ROHM fast switching

diode and choke transformer, and the 300B heater uses DC ignition with a DC power supply for
a complete design for low noises.

Furthermore, the power transformer does not come into direct contact with the chassis having

anti-vibration rubber which is adopted for MA-5000 in between.
This prevents unwanted vibrations from being transmitted to the chassis and contributes to further
reduction of noise levels.

6. Preamp function

With three inputs being provided and by using ALPS audio volume controls, it can be easily used as

an integrated amplifier.
Also, input 1 can be used as a power amplifier in DIRECT mode without using the volume control.
