subsitute for EL2001?

[tempus fugit]

Hey all;

I'm looking at building the function generator here:

http://www.armory.com/~rstevew/Public/SoundSynth/FunctGens/hsfglc11.gif

the problem is, I can't locate an EL2001 (i've got the data sheet - it's a
"low power, 70MHz buffer amplifier". Can anyone point me to a substitute
(preferably available from Mouser)?


I've hunted around, but haven't really found anything that quite matches the
EL2001.

Also, do I need BNC connectors (i.e., with 50ohm cable) for the function
generator, or will any connector/impedance do?

Thanks
