Instructions
-Always use good quality 25 - 35 watt soldering iron. High heat / high wattage soldering iron will harm PCB
as well as components.
-
Make sure Correct polarity of all Polar Capacitors and Semiconductors.
-
Securely mount Power Amplifier IC with insulator on suitable Heat sink.
-Before powering on for the first time check for any short circuits between power supplies, ground and
output.
-
Apply power without any output load (Speakers) and input signal connected.
-
If there is no Bang or Smoke and nothing is getting too hot or burning, Eureka.
-Now connect the load ( Speakers ) and power on, there should be no Noise or Hum without input signal, if
there any Noise/ Hum, power down and recheck.
-
Now apply the Input signal and enjoy
