Substituting 2n5485 JFET?

[jfrabat]

I saw a different schem that used quite different transistors.

Couldn't it be a 5458  spelled wrong??

Maybe...  but I do not have 5458s anyway, so I will give the NTE a shot.  I can always replace it if it does not work...

Why not get the original?

Tayda stocks them for $0,47...

$0.47 for the transistor and $35 to ship to Costa Rica...

Hi!
You can try to apply BF245A, BF245B, they are very similar to 5485.

J113, or j112 should work, check datasheets. They are in the right Idss and Vgsoff range. And they are fairly easy to obain (Farnell)
