Does anyone know where I can get a double gate fet like the old 40673? I
know Ocean State has it but it's kind of high $8.50, I know their are
others like the 3N201 and BF900. But can't seem to find them anyplace.

I think they are now over $10 each in Ocean State's newest catalog I
just got in the mail!

I saw a web page somewheres showing that you can simulate a dual gate
mosfet with two jfets in series cascade. J310's work well in this
circuit and they are cheap.
