yes that WAS true BNR. Upon system power up, line voltage would sag to below 100 VAC then recover.

Scratch your head w/this:
Upon purchase, the 975 ran for 3 weeks w/out a hitch w/the same amp config* w/a damaged neutral w/a gas dryer. Switching to electric dryer made it poop. Didn't learn about the damaged neutral till after the 2nd failure.

what does that mean?

I doubt that now. Does anyone think a 116VAC sag is a "brownout?!" Sidenote: we did experience a 2 second blackout just before lights out last night. See "Scratch your head" above.

Ponder this this solution: For all low draw equipment, looking at a Panamax conditioner on the Polk flea market for surge protection. Further considering 1 or 2 UPSs. One small (100 VA?), fast acting UPS for the 975. The other to power the everything else. The Xbox, TV, and cable* see the most use, the Xbox drawing over half the combined 6** amps or 725 watts? CD and Blu Ray about 1A each***.
* on all the time
** taken from their PSs
*** Xbox off when they're in use.

During the last failure the Belles Amps (6 amp fuses) were powered by the Furman out of the other 20A outlet* - remember it* has 2! The Hafler (3A fuse) actually wasn't turned on for some reason.

The amps combined draw based upon fuses = 19A*(!) though in actual use their draw probably 1/2 or less. Note: I will add 3 more 3A amps by the time I finish the bi-amping & tri-amping. Before that I will use the Furman** delay turn on feature (2-3 sec) to prevent popping the breaker. They'll, of course, share the dedicated 20A feed but none of the above mention UPSs or protection. I will get the amps protection in due course - one problem at a time
* Audio Pro not in equation - family game engrossed as I type
** BTW I have two Furman Miniport 20s - 20 stands for 20A

yup

Thanks for reading this far, you guys are the best! Tony
