【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. A standard model of a full-fledged vacuum tube line amplifier. The 6K4 is used as the standard included vacuum tube. Enhanced power supply stabilization circuitry, improved signal-to-noise ratio. Equipped with a buffer circuit using operational amplifiers. AC adapter required (sold separately) DC12V/1A DC jack 5.5mm x 2.1mm (center positive) New batch released on December 11, 2024. - Replaced the output coupling capacitor with a TDK EPCOS MKT capacitor. By employing capacitors that offer high-resolution, high-quality sound without the harshness that can lead to listening fatigue, these headphones enhance the sound quality of the vacuum tubes. - Other minor parts changes There are no changes to the main board circuitry this time. Vacuum tube line amplifier FX-AUDIO-『TUBE-00J』 This product is a standard model of a full-fledged vacuum tube line amplifier newly designed with modern ideas. Easy-to-use 12V single power input (can be powered by a 12V AC adapter) Rather than being a superficial vacuum tube-look audio product, it inherits the high-quality sound of the TUBE-01J as a solid audio product. Furthermore, it incorporates new improvements and circuitry streamlining based on the experience gained from developing the TUBE-01J and TUBE-03J. In terms of cost-performance, including sound quality and overall satisfaction relative to the price, I can confidently recommend it! If you don't already own a vacuum tube line amplifier, you should definitely give it a try! Open up a whole new world for yourself. [How to use] Please use this product by placing it between your audio playback device (such as a CD player, DAC, or silicon player) and your power amplifier. INPUT: Connect to the analog output terminal of a CD player, DAC, etc. OUTPUT: Connect to the analog input terminal of a power amplifier, main amplifier, etc. *Please refer to the included instruction manual for detailed usage instructions. [Caution] *AC adapter sold separately. Please purchase the recommended AC adapter at the same time. *This unit is a preamplifier. A separate power amplifier is required to connect to passive speakers (which do not have a built-in amplifier). *This unit does not have a built-in phono equalizer. To connect to an analog turntable, you will need to connect to a turntable with a built-in phono equalizer or purchase a separate phono equalizer. *The device contains high-voltage components, and contact could result in electric shock and injury. It could also cause a fire, so never disassemble or modify it.
