220V 20W 40W power transformer for electronic tube machine 230V-250V 20mA 6.3V -8V/ 2A
20W
1: 220V 20W power transformer for electronic tube machine, used for 6J1, 6N1, 6E2, 6N3, 12AX7 and other electronic tubes.
2: Input 220V/235V AC, and there is an anti-interference shielding grounding wire between the primary and secondary.
3: High voltage output 230V-250V 20mA (bridge rectifier), filament output: 0-6.3V -8V/ 2A filament, can be used for three-terminal regulator block to stabilize.
4: There is a function of marking the lead on the transformer, which is suitable for the use of the front-end power supply.
5: The high-quality EI Z11 high permeability four-hole iron core is wound, and the effect of winding the power transformer with the iron core material of the amplifier output transformer is also greatly different. It has high efficiency, low iron loss, low temperature rise, low magnetic leakage, and the disadvantage is high cost. Z11 four-hole iron core is more than three times more expensive than ordinary iron cores, so the cost of using Z11 material to produce power transformers is high.
6: Iron core size: 57mm×48mm×30mm stack thickness, each piece is only 0.35mm thick, with high magnetic flux. Riding clip type iron hoops fixed.
7: Outer dimensions of transformer: length 60mmx width 60mm and height 50mm. The center hole distance of the fixed two is about 73mm, and the weight is about 0.74Kg.
40W
40W power transformer for tube amplifier: high-quality power transformer, red bull clip or riding clip vertical fixed, sophisticated technology, sufficient materials, pure copper copper enameled wire, low temperature rise of the transformer, no vibration. Iron core: 66×35mm, weight 1Kg.
Input 220V-235V AC, ground wire for primary and secondary shielding, output: 0~5V~6.3V / 2A filament, 0-8.5V-9.5V/2A, 0~250V~280V / 50mA high voltage, suitable for front tube transistor Regulated power supply is used.
