Note:
1. This product is dangerous for bare boards with high voltage circuits. It must be purchased by people who will use it. Our store does not bear all the consequences caused by the use
2. For long-term high-power use, please add fan air-cooling, power supply with over-temperature shutdown protection, protection for lock-up protection, you must disconnect AC power and wait a few minutes before re-energizing to start. The power supply is a true LLC power supply, and the resonant circuit is a high frequency positive mystery wave. It is not an ordinary square wave switching power supply. It is very suitable for power amplifier use, and the effect is good.
3. Each power supply has been tested before shipment, and all the shops that burned transformers, tubes and ICs are not responsible for this.
