bestbang4thebuck et al,

I'm just a dumb mechanical / aeronautical engineer so I'll leave the heavy electrical stuff to you pros.

However I wonder why you would not connect all of your low-current components to a UPS - so that there is never an unexpected power loss that affects any of your critical components? I run a pretty hefty one for that reason (and to never have to reset the dang clocks on my VCRs!). When the power goes out, everything but my amps stay powered up - long enough to do a controlled shutdown. (Even the rack lighting is on the UPS so that you can see what you're doing when the lights go out - figured that one out when I did my first test run!)

Regards.
