【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.
Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.
■ Plug Type
This product uses a Japanese plug (Type A or B).
A plug adapter may be required depending on your region.
■ Transformer Requirement (Very Important)
A transformer is required for safe use.
A plug adapter only changes the plug shape and DOES NOT convert voltage.
Using this product without a transformer may cause serious and irreversible damage.
■ Buyer Responsibility
As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.
■ No Return / No Refund Policy
We do NOT accept returns or refunds for:
・Voltage mismatch (including 120V and 220–240V environments)
・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
Please ensure full understanding of the above before purchasing.
Use only under the correct voltage environment.
This amplifier utilizes one 12AX7 and two 6BQ5 vacuum tubes, employing a pentode connection, cathode negative feedback circuit, and Class A single-ended amplifier configuration to deliver 3W x 2 output. Enjoy the warm, rich tone unique to vacuum tubes that cannot be achieved with transistors. *Please note* If you replace the vacuum tubes yourself, the warranty will be void. Please be aware of this beforehand. For reference when replacing vacuum tubes after understanding the above, please refer to the compatibility chart posted on the brand website.
This unit features three analog input terminals, including a PHONO input. You can connect not only record players, which are well-suited to vacuum tubes, but also CD players, Bluetooth receivers, and other devices. It also has a headphone output (Φ3.5mm), allowing you to enjoy it as a headphone amplifier as well.
Equipped with a tone control function that allows you to adjust the sound to your liking. This unit employs a shelving characteristic circuit for sound field correction, allowing for optimal adjustment according to the environment (sound field) and volume, so you can enjoy great music. Furthermore, an ON/OFF switch is provided to skip the tone control circuit itself.
The unit's design centers around the soft glow emitted by vacuum tubes, and the control panel is made of wood. It not only delivers a warm sound quality, but its design also evokes a nostalgic atmosphere in any room where it's placed.
Its compact size, measuring 200mm wide x 290mm deep, fits within the A4 size. It can be easily placed on a TV stand in the living room, a sideboard in the dining room, or a desktop in a study.
In this digital age, we wanted to deliver a product that allows you to easily enjoy the deep, warm sound unique to analog (vacuum tubes). The "SWL-T20-SD" vacuum tube integrated amplifier, a meticulously crafted "purely Japanese-made" product, was born from this desire.
■The warm tone unique to vacuum tubes This amplifier employs one 12AX7 and two 6BQ5 vacuum tubes, and features a pentode connection, cathode negative feedback circuit, and Class A single-ended amplifier configuration to deliver 3W x 2 output. Vacuum tubes have long been obsolete in general electronic devices due to the advent of small and inexpensive transistors (semiconductors), but they possess a unique charm that cannot be expressed by transistors acoustically. Enjoy the warm and lustrous tone unique to vacuum tubes to the fullest.
■ Abundant input and output terminals for connecting to various devices such as record players This unit is equipped with three analog input terminals, including a PHONO input. In addition to record players, which are well compatible with vacuum tubes, you can also connect CD players, Bluetooth receivers, and other devices. If you want to enrich the bass, you can connect a subwoofer to the SUB OUT terminal. It also has a headphone output (Φ3.5mm), so you can enjoy it as a headphone amplifier as well.
■ Tone control function to adjust the sound to your liking The tone control is an acoustic filter for adjusting the high and low frequencies, and can have a significant effect depending on how it is used. This unit employs a shelving characteristic circuit for sound field correction, allowing for optimal adjustment according to the environment (sound field) and volume in which the equipment is placed, so you can enjoy great music. Furthermore, an ON/OFF switch is provided to skip the tone control circuit itself. It is a fact that even the best circuit will lose some of its clarity if the signal passes through several circuits. With this skip switch, you can enjoy a more direct sound closer to the original source.
