TL072 Substitute in Shaka Tube?

[eliktronik]

Can anyone tell me whether I can replace the tl072 in the Shaka Tube w/ any other commonly availabe op-amp? The TL-072 is described as a J-FET input op-amp.. Is there any way I could use another op-amp and jfet's to simulate the tl's behavior? I know this is kind of a dumb question, but I don't feel like mail ordering just that chip... Thanks in advance.

I haven't looked at the schem but I guess you can sub for any of the other 8 pin ops that share that pinout which inlude, but not exclusive to,the TL082/62,4558,5532 and the LF353.
There's more but I forget.
