Amplifier Relay Problem at Catherine Trowbridge blog

Amplifier Relay Problem. Sometimes if a relay is getting poor contact,. It could be the relay. Very simply, you want one rated for 120/240 vac anyway (a common rating as most are for mains use). The only purpose of these likely, from reading the manual and given the position on the board, is to mute the speaker output on startup for six seconds, or when pressing the mute button. The next thing is current. Which switch causes the audio to come back? This then causes a small power transistor to switch on and energise a relay with contacts in series with the feed from the. I am driving a 9v relay from the output of a comparator (ldr sensor) and the relay gets damaged due to rapidly changing voltage from the comparator when light on the. The coil of the relay is powered by the amp's power supply, but with a short delay of a few seconds to provide time for the amp. There is one large relay on each back corner of the amp. When i powered up the amp this morning (it's 12°c / 54°f indoors), it took a full 40 seconds before the second relay clicked and. If the amp is working normal (no dc out at both output), the q706 will turn on and drive the relay(turn on speaker output) to ground when the amp is working(playing music). They may alternately be triggered by a protection circuit.
