Super quality PCB. Solder pads are corrosion resistant. Soldering quality is very important in audio and high-frequency circuits. Thanks to the quality lead finishing on the Pads on the PCB, the soldering process is high quality. PCB quality greatly increases the operating performance of such circuits.
Technical Details:
IRF540N IRF9540N Mosfets are used on the output stage of the circuit. LM393 is used for the driver.
You should use an LCR meter to make the coil in this amp circuit. Because the sound quality is 50% dependent on the coil and 50% on the amp circuit.
Series light test:- After complete this board don't forget to series light test. When you will on this amplifier via series light, it glow for some time (1 - 2 sec). Then series light will turned off fully. If the series light will fully turned off, then check the voltages.
Check Voltages:- Check Speaker Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect preamplifier to input and connect speaker to output.
Power Supply:- For get best performance of this amplifier, you use 30-0-30V 5A Transformer.
