Tube Amplifier Power TransformerTube Amplifier power amplifier front stage switching power supply board 6.3v 3.5A 250v 0.1A-Input 100v-240v

The power circuit adopts wide voltage (100v-265v) designThe switching power supply output power 60wInput voltage 100v-240vOutput the first group 6.3v 3.5AOutput the second set of 250v 0.1AThe size is 120mmX55mmMounting hole size is 112mmX47mmThis product is suitable for the pre-amplifier and small amplifiers, eliminates traditional hum, stabilizes the filament voltage to ensure the safety of the tube. It is a special switching power supply jointly developed by profeional R&D switching power supply engineers and 30-year amplifier technicians. The tube amplifier power supply system and audio quality have been yzed and compared before production, and the quality is very reliable. All s adopt high-precision, non-inductive, high-quality ch s, and the output adopts high-frequency, low-resistance and high-quality to ensure that the switching power supply is more stable. The power circuit adopts a wide voltage (100v-265v) design and has been on the market for more than 5 years. It has been trusted by peers and enthusiasts. The s volume has exceeded 1,000 units, and the fai rate is over 99.99%. The output power of this switching power supply is 60w, which replaces the traditional iron-core power frequency transformer (power frequency transformer efficiency is 70%). Its advantage is to soe the difficult-to-handle hum of traditional transformers, and to soe various faults caused by voltage instability. It is suitable for tube amplifiers. Power amplifier, pre-amplifier, tube amplifier, tube amplifier are the easiest for beginners to aemble the tube amplifier, which changes the quality of the tube amplifier.
