This product is a special switching power supply developed by professional R&D switching power supply engineers and more than 30 years of amplifier technicians. For the power supply system and audio quality of the amplifier, the final analysis and comparison are made, the quality is very reliable, and all the resistors are used. High-precision, non-inductive high-quality chip resistors, high-frequency, low-resistance and high-quality output capacitors ensure stable switching power supply.
The power circuit adopts wide voltage (100V-265V) design, is more suitable for export products, has been put on the market for more than 5 years, and is trusted by peers and fans. The sales volume has exceeded 100,000 units and the failure rate is 99.99%. Thanks to the old customers. Support, trust, the company has accepted the advice of the old customers have developed new products, waiting for the quality is stable, in the short-term have been placed on the market, please pay attention to new and old customers,
The switching power supply has an output power of 60W, which replaces the traditional iron core power frequency transformer (70% efficiency of the power frequency transformer). Its advantages are to solve the ac noise that is difficult to handle with traditional transformers, and to solve various faults in voltage instability. It also brings convenience, reduces a lot of freight, improves the working efficiency of electricity, reduces the production cost, adapts to the amplifier, preamplifier tube amplifier, and tube amplifier. It is the easiest for beginners to assemble the amplifier to change the quality of the amplifier.
