Thank you..... LIke I said, my circuit consists of a fuill wave and a 120VAC to 12VAC step down transformer. That is input to a full wave bridge rectifier and finally to a 12VDC regulator.I won't tell you the idea because it is not safe at all. Better to use a small 6VA transformer and a 1 Amps bridge rectifier to do the job rather get killed.
I think I'll just build and see how it goes.
thanks
