relay question for normster...

[jngreene79]

I'm building a relay board for 2 dpdt relays and I'm using your switching layout from your 6v6 build. I've got the Radio Shack 6-0-6 PT. It looks like you have the CT (black) wired between the diodes and one of the 6VAC leads to the junction of the caps. I wired the board according to the layout with no luck. I must be missing something. Are the lead colors reversed in your layout? Thanks, James

It shouldn't matter if the leads are reversed since it's just AC anyway. The circuit is a voltage doubler which is why I use the center tap and one leg. (Tape the other leg off. It's not used.) It should be giving your about 18VDC without a load. If you use both hot leads the circuit is about 30VDC. Whatever you do, don't ground the center tap. The transformer will get smokin' hot.

Thanks for your help, and your excellent layouts. -james
