• 1. The voltage at the measuring point (+) - (0) - (-) is unbalanced.
• 2. The polarity error (+ / - is, reversed) on the speakers, including the crossover system.
• 3. incorrect in taking the zero point (ground) power supply for tone control.

The power amplifier with "ticking" sound after turned off - This time.. the author will discuss about how to overcome the damage to the audio power amplifier, where the damage is marked by the "ticking" sound sound symptoms after the amplifier is turned off.

The power amplifier with "ticking" sound after turned off

There are 3 possibilities to overcome the amplifier's damage marked by the "ticking" sound after turned off:

1. The voltage at the measuring point (+) - (0) - (-) is unbalanced.

Check each polarity using a multimeter.

The cause could be due to an unbalanced transformer secondary voltage or the capacitor is damaged or unbalanced power supply load (amplifier power supply).

2. The polarity error (+ / - is, reversed) on the speakers, including the crossover system.

3. incorrect in taking the zero point (ground) power supply for tone control.

Try to move the zero point (ground) for tone control to another main power supply point.

Find the other best points.
