Powervar ABC1200-11 power conditioner as often used in professional audio/video or medical applications. It contains an isolation transformer and surge suppression and is rated at 1440 watts (120VAC/12AMP) so definitely capable of handling speaker power amps as well as the rest of your system. This item is hospital surplus, although note that it's not the medical version of this unit (which would be ABC1200-11MED).

It's scuffed up from its previous medical application, but functions perfectly, so I'm rating at as "good," but note that purely cosmetically it would be more of a "fair."

PREFERENCE GIVEN to LOCAL PICKUP in the LOS ANGELES area. You will save a LOT of money on shipping if you can pick this up.

If I don't get any local pickup offers, I'm willing to ship it, but I'll ask you to cover shipping costs as well as materials cost (double boxed, packing materials). It weighs 40 to 50 pounds so it will be something like $100 to 150 to ship by UPS or FEDEX.
