using preamp set up with stereo power amp?

    What I am looking at trying to do is run a stereo power amp into a swr 220 head. Bypassing the power section of the swr and just using the preamp. But the stereo power amps I was looking at are only bridgeable at 8ohm. I want to run two 8 ohm cabs off this set up. Is there a way I can run both sides of the power amp into a single preamp without bridging?

    Thanks for any help

    Sure. Most stereo power amps have a stereo/mono switch somewhere, so just take the line out from your SWR preamp and plug it into either input of the stereo power amp and you're good to go. You can run each channel's output from the stereo power amps into separate 8 ohm speakers. By running them this way you'll probably get close to the power you'd get from bridging, maybe not quite as much, but more importantly your amp will be safe.

    my power amp (old Carver) doesn't have a mono switch, so I just use a Y-cord from the pre amp to each side of the power amp.
