Improved JFET Matcher question

[Hiwatt25]

Does the IC in the Improved JFET Matcher have to be an LM741?  I ask because I don't have one and I'm wondering if something else that I have laying about might do the trick. 

Thanks!

I think any of the common op-amps will work.

Gotta love Ebay, I found 10 of them for 4.50 including shipping and the seller is right up the road in Mass.  Thanks for the reply.

Any single op amp should work fine, such as a TL081/TL061/TL071, etc.

Great, thanks again.  As it turns out I've got some TL071's so I can build this sucker tonight and get to matching!  Now what am I gonna do with 10 LM741's

Well, this thing will take care of 3 of 'em anyway!
