Howdy y'all. It's been a loooong time since I've hung out here. I hope everyone's been doing well.
Looking for a bit of advice. A while back my right channel went out. I went through all the wires checking for something loose and accidentally bumped the power switch on the amp. As soon as I did the channel came back.
Now the same thing happens intermittently. Quickly pushing the power switch always brings it right back. It doesn't bother me that much but I'm a bit worried that there may be a failing component and by ignoring it I may cause serious damage.
What do you think?
Sounds good to me...

    Sweet. New switch is no big deal. I thought it odd that only half the amp would cut due to a failing power switch but I suppose it actually is a single switch switching two independent sides. Makes sense.
    Sounds good to me...

    P.S. If you ever get the chance to pick one of these amps up, don't hesitate. This is the ONLY issue I've had with it in 10 years. This despite my regularly abusing it. (I've even used it to simultaneously power sets of Infinity RSII, Maggies, Monitor 7, and Monitor 10 at stupid volumes for house parties.... don't tell anyone)
    Sounds good to me...

    A friend with one of those amps can't turn it off via the power switch, it does nothing when pushed.

    Ha! I don't see the problem there. Why would you ever want the music to stop???

    Rev. Hayes,
    If there was ever a time to come back on the forum, now is the time.

    Harry speaks the truth. Only problem is it's giving me GAS. I thought I was finally cured...

    I have replaced the power switch on my ex-442 at least 6 times since I bought it new ..
    They are notorious for failure.
    Last time I bought several as back ups .
