Product details
In the world of audio amplifiers, wide kinds of semiconductor amplifiers, tube amplifiers, etc. are released. Therefore, the respective audio features can be enjoyed as a hobby. The tube power amplifiers have a tube called "fine tube" having a reputation for sound quality and in 2017, Phasemation has released the monaural power amplifier, MA-1500 composed by a single-ended circuit adopting 300B which is the best tube among vacuum tubes and a circuit strongly driven by a transformer-coupled circuit. In 2024, in order to express this significance to a wider audience, we developed the SA-1500 stereo integrated amplifier with a single operation of a 300B single-tube and ensuring a 9W output.
Output tubes 300B optimally driven with 6SN7
The 300B output tube is a self-biased single pure class-A operation, and 6SN7 is used in a two-stage amplification circuit to demonstrate the original quality of the 300B in the simplest possible operation, driving speakers with unshakable stability
Non feedback amplifier with triode tubes in all stages
Two-stage 6SN7 +300B all-stage triode tube to achieve the dynamic and expressive music playing that is only possible with a non-feedback circuit
Output transformer made by Lundahl, Sweden
An output transformer manufactured by Lundahl of Sweden is used because it is appropriate for the configuration of this unit and has the most suitable sound quality that Phasemation is aiming for. A shared terminal is supplied to optimally drive the speakers from 4 to 8 ohms
Independent dual power choke transformer configuration
The power supply circuits for the left and right channels are powered by independent choke coils, eliminating mutual interference between the left and right channels and providing clear amplification of signals from minute levels to high-power signals.
A thorough low noise design
This is thoroughly designed for a low-noise; it is designed with a rectification circuit with a ROHM high-speed switching diode and choke transformer for the high-voltage power supply and the 300B heater using DC ignition with a DC power supply. Furthermore, the power transformer is floating from the chassis using anti-vibration rubber used in the MA-5000. This suppresses the transmission of unwanted vibrations to the chassis and contributes to further reduction of noise levels
Power amplifier direct function
Three RCA input terminals are provided. In addition, the “DIRECT mode” is provided on the “INPUT1” terminal. By selecting this “DIRECT mode,” the music signal passes through the volume control, allowing the unit to be used as a “stereo power amplifier” with even higher purity and a greater atmospheric expression.

How is my order processed ?
Once we have received your order and your payment, we issue you an invoice that will be mailed to you with a reference number for your order. Once your order is ready : it will be dispatched to you with insurance and tracking number.
Which payment methos are available in the Online Shop ?
You can choose between Paypal, bank transfer or Credit Card. Please take in consideration that payment via bank transfer will slightly delay the processing of your order as we have to receive your funds on our bank account to confirm your order.
Why are there different estimated delays prior to sending for some of the products

Please keep in mind that we are a 100% human company working all over the Old World (Europe) and that we do commit to deliver you the best made / best quality product available, and to insure that : this can take some time.
Of course… some of our products are in stock !
Can I specify a courrier for my order ?
Yes you can ! Just drop us a line in the « additional remarks » of your mail order. This may add additional fees to your order. We can work with DHL, TNT, FedEX, UPS, French La Poste or Chronopost.
What if I have received the wrong item ?
In the very unlikely case this would happen just send us a photo of what you received and we will send you a courrier to fetch the item back. Once we have checked it out, we will send you the correct item.
My items are not up to specifications, what should I do ?
This is highly improbable as we use the most modern techniques to insure that our products are up to specs. In fact we even have a dedicated person checking that every single item is in perfect condition prior to shipping. Of course it can happen, but we doubt it seriously.
