----------------------------------------------------------------------
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Adopting 12AX7 (1 tube) and 6BQ5 (2 tubes) vacuum tubes, a pentode connection, cathode negative feedback circuit, and a class A single amplifier configuration provides an output of 3W x 2. Enjoy the warm, lustrous tone unique to vacuum tubes that cannot be expressed with transistors. *Note* Please note that if you replace the vacuum tube yourself, the warranty will not apply. Please refer to the compatibility table posted on the brand website as a reference when replacing the vacuum tube after understanding the above.
This unit is equipped with three analog input terminals including a PHONO input. You can connect not only record players that are compatible with vacuum tubes, but also CD players, Bluetooth receivers, etc. It also has a headphone output (Φ3.5mm), so you can enjoy it as a headphone amplifier.
Equipped with a tone control function that allows you to adjust the sound to your liking. This unit uses a shelving characteristic circuit for sound field correction, allowing you to make the best adjustments according to the environment (sound field) and volume in which the device is placed, allowing you to enjoy great music. Furthermore, we have provided an ON/OFF switch to skip the tone control circuit itself.
The main body design focuses on the soft light emitted by vacuum tubes, and a wooden panel is used for the operation section. Not only the warm sound quality, but also the design will give the room a nostalgic feel.
Compact size that fits into A4 size with width 200mm x depth 290mm. It can be easily installed on the TV board in the living room, sideboard in the dining room, desktop in the study, etc.
In this age of digital, we want to deliver products that allow you to enjoy the deep, warm sound that only analog (vacuum tube) can offer as easily as possible. The SWL-T20-SD, a carefully selected ``Purely Made in Japan'' vacuum tube integrated amplifier, was born out of this desire.
■Warm tone unique to vacuum tubes Adopts 12AX7 (1 tube) and 6BQ5 (2 tubes) vacuum tubes, and with a pentode connection, cathode negative feedback circuit, and class A single amplifier configuration, an output of 3W x 2 can be obtained. Vacuum tubes have long since ceased to be used in general electronic equipment due to the advent of small and inexpensive transistors (semiconductors), but they have a unique charm acoustically that cannot be expressed with transistors. Enjoy the warm and lustrous tone unique to vacuum tubes.
■A wealth of input/output terminals that can be connected to various devices such as record players This unit is equipped with three analog input terminals including a PHONO input. You can connect not only record players that are compatible with vacuum tubes, but also CD players, Bluetooth receivers, etc. If you want to enrich the low range, you can also connect the SUB OUT terminal to a subwoofer. It also has a headphone output (Φ3.5mm), so you can enjoy it as a headphone amplifier.
■Tone control function that allows you to adjust the sound to your liking Tone control is an acoustic filter that adjusts the high and low frequencies, and depending on how you use it, you can get great effects. This unit uses a shelving characteristic circuit for sound field correction, allowing you to make the best adjustments according to the environment (sound field) and volume in which the device is placed, allowing you to enjoy great music. Furthermore, we have provided an ON/OFF switch to skip the tone control circuit itself. No matter how great the circuit is, it is true that if the signal passes through several circuits, the freshness of the sound will deteriorate. With this skip switch, you can enjoy a straight sound closer to the sound source.
