Alpha Dog & 2n5458

[Timko]

Sorry for the deluge of questions this morning, but I was about to check out from Smallbear with some 2n5458's in my cart and it told me they were out.  I looked at the schematic for the AD and it appears that JFET is being used as an output buffer.  When designing the Kansas City Prairiemaster, I used a MPF5102 JFET as an input buffer for the clean boost side of that effect.  I assume that since the 5458 is being used in the buffer configuration, then any standard JFET would work in place of it (as long as the pinout is the same)?

Yes, I've used various Jfets as output buffers in Rat builds, never had a problem! Lately I've used cheap smd 5457 from tayda, again with no issue

Thanks!  I placed my Tayda order literally seconds before my Smallbear order or I would have gotten some more 5457s .  The good news is that I got a bunch of the PF5102s when Mouser was selling them and you couldn't track down the 54xx's affordably for buffers so I'll sub in one of those.
