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.

Though not if you buy them from MkV in the UK where they want seven
quid! What's that...$11 for a lousy common JFET. Happily they're
readily available elsewhere for a fraction of that ridiculous price.
Yeah, the cascade solution's good if space permits.
