: : Looking for transistors for a 6000
: : FPN4250 and GES97
: Ahhh Yes! the 4250 is a low noise PNP, which is also a 2N4250 or MPS4250 which you can evidently get at
: http://www.web-tronics.com/mps4250.html
: I thinkn that was the current source in the mic pre. I gotta get those schematics up on this site! Coming up soon, I promise!

: The GES97 was an NPN,around 40 Volts Vceo I think, but we used them in theses companies cause they were "OK" and cheap! The pinout as I remember was BCE not EBC like a 2N2222 etc...
: boB

Thanks for the info.
Are you saying that a 2n2222 or any AF NPN with a 40V collector to emitter transistor will work if I insert it as a bce?

Thanks again
Fred
