【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. 【Fully Balanced Hi-Fi Vacuum Tube Preamp】Low noise, low distortion, wide dynamic range, faithful amplification and transmission of signals, fully balanced circuit design/high-end op-amp chip/rich vacuum tube tone, signal-to-noise ratio (SNR): ≥ 112 dB, distortion (THD + N): 0.003%, dynamic range: 109 dB. 【ECC83 Vacuum Tube】Noble sound (PSVANE), boosted preamplifier circuit, the tubing power reaches 180V, allowing the tube to reproduce in optimal condition.
