    Failing amp?

    I have a Optimus STA-20 home stereo amp/receiver.

    My question is, is the amp failing? Reason I ask is because randomly the left channel will cut out and just crackle until I smack the amp.

    Its not lose or bad wires, I have checked/replaced them all.

    I have it wired like this..

    "Phones" to my computer speakers
    "CD/TAPE" from my PC and I use the RCA "TAPE" output to a Fisher 300watt amp that runs a 12" car sub.

    also, I don't have the problem with the speakers when they are plugged directly into the computer, only when plugged into the STA-20 amp.

    if you slap it and it starts working, it's failing.

    Re: Failing amp?

    Does it have volume controls for each channel? I'd spray DeOxit in all the pots and switches...

    Re: Failing amp?

    Nope, both have a volume control that controls both channels at the same time. But they do have a balance control. I don't have any DeOxit, would it be a good idea to just bust out the soldering iron and sweat each solder joint?

    I'm normally pretty **** good with electronics but this is one thing that's been f-ing up for a while that I haven't taken the time to fix lol

    It sounds like you've got a loose connection somewhere, I'd check everything you can see on the left channel.
