Heathkit made a piece of equipment back in the '80s that could control AC power going to multiple pieces of gear. It was designed to sense when one unit was turned on by the operator, then it would connect AC power to all units plugged into it. Does anyone know what this was called, or better yet, the model number? Is there a modern equivalent?

There is a project in a 1970s Popular Electronics mag. I'll dig it out for you. It's triac based so you don't need a sensitive relay.Another idea. Does your preamp have a switched AC outlet? You could use that to control a power relay.

Thanks, that's an interesting site!

Simple (crude, even) but effective.
I actually have one of these by my living room chair -- to throttle the vampire power consumption of my trusty laptop :)

I was actually hoping to locate a schematic for the Heathkit so I could DIY one. Found the unit on eBay though, complete with manual. Not cheap, but less than I could build one for, especially with US components. Yay!

I am curiuos... what will this do that a power strip won't?
It will allow me to hide the strip and turn everything on with the preamp power switch. More convenient than turning everything on manually, and it keeps a lot of messy cabling out of view. :)

I am confused. If you use a long strip and tuck it away except for the end with the power switch you only have to push a single button if you leave the switchs for the indidual pieces in the on position. Everything comes on at once.
Power strips aren't exposed or easily accessible in my cabinet. They reside in a bottom section at the rear that's designed for this purpose.

Got it.
I'm probably the only person on the planet crazy enough to consider DIY'ing one of these. Here's the schematic, just in case I'm not alone. :)

I remember seeing a construction project in the old "Popular Electronics Magazine" about a similar device. This was back in the late '70s or early '80s, I don't remember the exact issue but I did build one and it worked well.
Hope this helps.

Mrs. H uses a power strip with one master and a bunch of slaves. If the master's on, the slaves are, too.
She really doesn't like "vampire power supplies" in digital equipment (like laptop and phone chargers) usin' her kilowatt-hours! :-)
The HT crowd sometimes uses similar (pricier and nicer looking) gizmos to turn on peripherals or whatever when the BIG SCREEN is brought to life.
Try:
Amazon search for HT power management

I don't recall the Heathkit version. I think there may be a modern version. The idea was to plug your table saw into one outlet and you shop vac into the other. When you turned the saw on, the vac started automatically.
