6J1 Tube amplifier hifi class A power Electronic DIY kit | Игрушки и хобби

Model: 6j1 tube (replaceable models 6AK5, 6AU6, 5654, etc.) Channel type: 2.0/stereo Working voltage: AC AC12V 0.8A or above Power interface: 5.5*2.5 plug Circuit board size: width 77 x depth 75 x height 57MM Whole machine weight: 87 grams (with copper pillar) Bile preamplifier, bile buffer function: added to the digital sound source such as The working principle of the power supply: When the power is turned on, the tube filament begins to heat up. At this time, the step-up starts from zero voltage. When the tube filament is hot, the step-up is just completed, so this is the same as the bile rectifier, 8 470UF The capacitor filter is very clean, and the excellent power supply system will not have hum, the filament is DC 12V power supply, and the filaments of two tubes are connected in series. The use of DC filament is also to reduce noise.
