Title: ? on double d dist.input and output
Post by: donald stringer on November 22, 2003, 09:57:48 PM
I do not have any j_201 for in and outs. I was wondering if I could sub 2n-7000 instead? If that is a yes ...JOE DAV. has an bias schem up on his old stuff site for 2n 7000 could I just sub those in. Thanks for the help. If not I do have mpf 102 or 3819 in order to keep it closer to the runoff groove schem.

Ansil I got your package and found the 4049, I put in sockets and I think I might try the 2n 7000. Thanks for the stuff, and the chips that was an unexpected surprise. What are those trans. c2383?

I'd try the MPF102 or 2N3819 first.  Watch the pinouts!
