surg protection / high output amps

I just bought this old old Power conditioner,

a desirable feature, besides protection, is the sequenced time delay, turns accessories on first, then 10 secs later powers the amp(s). Turns off amp first, delays 30 secs then turns off accessories.

probably too small for you, just thought I would mention that feature.

A friend has this currently available one, big enough?

I like the whole house idea too, 

new/used

after I bought mine, I read that IF they have dealt with spikes, repeatedly, there may be damage ... to parts within, never occurred to me, just passing what i read along ..

the adcom ace-515 is an AC Enhancer.

I took the cover off, all look like factory new (no mice ate these wires), nothing burnt from prior lightning strikes, ....

One switch for entire system is handy. It filters/enhances/prevents hash from it's power input, and 7 outputs.

What it does, and does well, is separate 2 switched amp outlets from 4 switched devices, and has 1 unswitched pass thru outlet.

It has an automatic turn on time delay of 10 secs for the 2 amp outlets to come on after the devices , and a 30 second time delay for the amps to turn off first, 30 secs for them to discharge, then turns off devices with no thump.

Vintage, got lucky again.
