Item-Description

Product description:

Voltage range: AC12V-AC28V (2-wire), 50W or more (AC18V 120W transformer is recommended)

One channel is up to 25W, one board and one channel.

PCB size: 62mm × 129mm

Features:

1: Using 5200 high-precision high-current voltage regulator output, the output voltage is more stable! Beyond the LM317! Noise is even more inaudible

2: Input using a thin film audio capacitor, the sound is better!

3: T-oshiba big tube 2SC5200 output! This tube has a maximum power of up to 150W, which allows the 1969 to output a maximum of 25W Class A! More than 2N3055! !

Debugging method:

The 1969 commissioning is divided into static current testing and neutral voltage testing.

1: quiescent current has been adjusted to the home, the default 1.2A, you can change the quiescent current by adjusting the 202 adjustable resistance on the board, recommended 1-2A! In addition, the quiescent current needs to be tested in series with the current input port.

2: Midpoint voltage test, the midpoint voltage needs to be one-half of the power supply voltage, that is, the power supply is 18V, then the midpoint voltage should be 9V, the test uses the DC voltage file, the red test pen is connected to the output capacitor positive pole, and the black test lead is grounded. Line test can be! Adjust the 204 resistor so that the voltage is equal to half of the supply voltage

Note: The capacitor is a disassembled product, and the test works well.

Package included:

2PCS Amplifier
