I have a circuit for you to try. I built this in 1968,and had marvelous results. Circuit #13. I'd still have it, but a friend lent me one of those battery eliminators that looked like a 9V battery with a power cord attached. It was hot to the power line and non-polarized at the AC plug. I had the circuit grounded, so there was a big bang when I plugged it in with hot on the wrong side!
