Tube Preamp Switch Power Supply Valve Amplifier Transformer Cattle 95V-265V Output 6.3V 280V with Shield Cover

1. The switching power supply has an all-aluminum alloy shell and a stainless steel shield, which shields various electromagnetic interference. ^^ 2. Comes with 5V Bluetooth decoder board power interface. ^^ 3. It comes with high-voltage delay synchronous rectification to reduce current impact. ^^ Make the treble clear, the middle pitch round, and the bottom noise clean. Let the problem of the lack of bass of the original tube also be solved, making your machine's bass dive more powerful. Use it on the 6P1 small single-ended front board to get better results.

Let your old machine get a new life. ^^ The high voltage output of this switching power supply adopts synchronous rectification technology and delay function, which can delay about 30 seconds, and the length of time can be adjusted by itself to avoid the impact on the tube when the filament is not hot.
