Many of the wallwarts that you have for old appliances have a stepdown transformer, diode rectifier (half or full), and capacitive filtering already in the "wart". No point building your own.

Yup, Doesn't everyone have a junk box with at least a half-dozen various old wall warts in it?

Or just get a SSR that uses 24VAC control like the Crydom A2450E.

You may have to pay retail for one of those, I haven't seen any cheap knock offs.

Buthcher a wall wart and get to cookin a batch. You can get a wal wart at any flea mkt for a couple of bucks and be brewing in a few minutes. I have a 24 VDC and a 5 VDc transformer and regulated power supply in my controller and got both off of ebay from the US for about 15 bucks a poece. They are chinese but I have an american warranty if I have an issue or failure. Your second idea was even better, just use the 24 VDC to run the SSR's and the controller for the on off function. Less parts= less chance of wiring errors or releasing the magic smoke.

Got two wall warts and going to check for more. Does the current mater at all? Seems to me that it would take more then .6A.

The SSRs should take practically nothing. What else is it you're going to run? There's probably a rating on it somewhere.

The input to the SSRs is optical, so it's an LED, so ~ 0.02 amps.

Well I don't see any ampere rating, but like you said 20ma is all it takes for a good time. Cool I must have spent multiple hours trying to figure this out and viola there it is. lol Thank god it wasn't a snake.
Thanks again for all your help.

Wall warts are simple and will do just fine. Looking for more power and voltage choices? Computer PSU. Grab one out of an old PC or salvage store, a switch, and a ceramic power resistor and you will have 5vdc and 12vdc all day long. Might also have 3vdc and some negative powers to make 8vdc and others odd one.
