Double gate FET
 

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.

The MFE201 is a good replacement for the old 40673.

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.

40673s can also still be purchased as the NTE 222.

Current dual-gate MOSFETs like the Philips BF991 shouldn't be difficult to
find. Packages are very small though, the BF991 is SOT243B.

Bill,

if you don't mind going international, J.Birkett of Lincoln has been
advertising the 40673s for £1.50 (around $2.50?) for the past two months.
Seems a good price to me for a hard to find device. Check out a copy of Radcom
if you can find on over there.

regards...

I was in Lincoln once and looked them up - piles of electronic junk, some of
it useful.
