Hi all,
Its quite some time since i perused forum, very happy to c the forum is highly active with lots of peoples and so many threads.
I am facing a problem with my car stereo amplifier. without having any catastrophic failure of any of the component, my car amplifier is going mute gradually in two or three hours. This especially happens if I dont use the carstereo for some few days. I can bring it back to working by connecting it to AC mains using a 12V adaptor and just by touching the input termingal with bare hand (a crude way of injecting the line noise and making a 50Hz hum) or by injecting a external signal of a little higher amplitude than the pre-amp out.
This will again go gradually mute after few days or weeks.
This I have observed with four to five other amplifiers also.
I find this happens most often after a rainy season and I doubt whether the humidity plays a role?(Mine is a coastal area)
I had changed all the capacitors of an amplifier ciruit once when I faced this problem, still did not help.
Any once has encountered such a trouble? Kindly share.
Thanks in advance.
