HiFi AUDIO AMPLIFIER CLASS A POWER BOARD

Description

HiFi AUDIO AMPLIFIER CLASS A POWER BOARD
The power supply board is modified to other circuits such as CD player, front board, tone board, decoder board, etc.
The sound quality and timbre are improved greatly, the details of high frequency are abundant, the mid frequency is smooth, the depth of low frequency is deep,
the depth is strong, and the elasticity is good.
The power acquisition chip is LM1723CN, the resistance is VISHAY, the filter capacitor EPCOS, the Weimar capacitor and the gold seal 2N6688.
This power supply board has excellent voltage stabilization performance, no drift and low temperature. It's a good choice for front-end power supply!
Four-wire AC input, two groups of four-wire DC output independently, can be connected to two groups of single voltage output, can also be connected to three-wire
double voltage   output, convenient and practical.
Input transformer must have 4-wire output voltage above 12V and below 25V, such as AC 15V-0 15V-0, DC can output 18-0 18-0 after the board is stabilized, or K point can be   shortened to 18-0-18 after the board is stabilized.
The two terminals in the middle share the ground wire. The output DC voltage measured is 4.3V-31.5V continuously adjustable!
Current output 1.1A, if you want more current,
you   can replace 5W/0.56 Euro resistance!
Size: 14.5cm * 11.2cm
