This power board is modified to CD player, front board, tone board, decoder board and other circuits. The sound quality and tone are improved greatly, the high frequency details are rich, the intermediate frequency is rounded, the low frequency is deep, the depth is strong, and the flexibility is good.
It is made of immersion gold, the power acquisition chip is LM1723CN, the resistance is VISHAY, the filter capacitor EPCOS, the Weimar capacitor, and the gold seal 2N6688
This power board has very good voltage regulation performance, no drift, and low temperature. It is a good choice for front-end power supply
Four-wire AC input, two groups of 4-wire independent DC output, can be connected to two groups of single voltage output, or three-wire double voltage output, convenient and practical
The input transformer must have a 4-wire output voltage above 12V and below 25V, such as AC 15V-0 15V-0. After the board is stabilized, the DC can output 18-0 18-0, or it can be short-circuited at the back K point to become 18-0- 18
The two terminals in the middle share the ground wire. The output DC voltage measured 4.3V-31.5V continuously adjustable The current output is 1.1A. If you want a larger current, you can replace the 5W/0.56 ohm resistor
Size: 14.5CM*11.2CM
