Trigger switched outlet

I would like to build an AC power outlet that would be switched from the 12V trigger of my preamp/processor. I am not an engineer in any way, but after reading and searching for a while I thought using an optocoupled triac would be a good solution with low parts count.

But... the optocoupled triacs can't handle much current, so it really has to control another bigger triac, but for some reason I don't like the idea of triacs handling big loads.
Then I thought of controlling an AC controlled relay instead. If this design would work I could get away with three parts (including the relay) to get it to work. And I could also control a really big relay if I want to and still only draw something like 10mA of the control signal.

The big question, would this design work at all (as I said, I don't know what I am doing, this circuit is more or less a guess)?

Thanks!
Robert

That is an optoisolated triac driver and cannot drive a relay directly.
It is a solid state substitute of a gate driver pulse transformer

I would still suggest u to google for 'ssr' and get some basics.

An optoisolated triac is a solid state relay. If you have no experience building with high voltage, choose the (pre-packaged) SSR. It might even be cheaper, certainly if you include the cost of your time.
If you look up datasheets and application notes on the optoisolators you'll find enough information to build one. My reference was the Motorola handbook from several years ago.
There's nothing wrong with triacs handling big loads.
