UPS, and i don't mean shipping

Well he could also have it that he runs only on batteries and switches the power supply off when listening. Not quite sure how long you might have without running into some money and a big row of batteries, and regulation as Mr. Aball has said. Then again with just the batteries I don't see it very difficult to convert your system to accept the DC. It is that DC/AC thing that is the tricky part.

Thanks for the info, folks! I gues i'm gonna throw it in the garbage. It's a shame though. There's a very big transfo and big capacitors in there. Maybe i'll keep the capacitors. Thanks again for saving me some trouble.

Sounds to me it does the same as the PS audio stuff. Check it out and see if works and let us know

snook2, i used to think the same, but having switched from an APC smartUPS 1000 to a Panamax MAX 5300 it was.... astounding. video looked better (remember how dependant NTSC is, clocking on 60hz) and i would say a general 15% improvement on sound (this coming from a skeptic who didn't buy into the speaker cable / power / ic thing for years). the problem is, computers like things REALLY clamped down and exact and that's what you get with these UPS units. audio, often you're best off plugging stuff into the wall (esp. with a hospital or audio grade outlet) unless you're worried about protection, but even good units like the panamax only offer like 5-10k of insurance which wouldn't cover many of the systems i've read about here).
