Behringer Europower EP1500

[sterjess]

I have an EP1500 with a strange problem. I'm pretty new to fixing amps, just replaced a shorted output transistor in an old hifonics falcon amp and thought I'd look into this Europower now. I'm using this on my home theatre system pushing 2 12" JL Audio subs, channel 2 comes in right away when I power it on, channel 1 won't come in unless I crank up the volume on my reciever to the point I'm almost clipping channel 2, then channel 1 will come in and sounds good after that. It will stay working if I turn it back down also, just won't come on until I give it a lot of volume. Anyone had a problem like this with these amps?

if its an old version might have on the one side a cable that looks like IDE cables .... often this plug gets loose ...newer models have glue one it
