Them 2N5952 And equivalents are hard to get a hold of these days anyone give SMD subs a go like the the J201? Just curious.
Try the 2n5457 SMD equivalents instead. J201 don’t have a compatible Vgs range.
Where you located? I may have somethingDamn near ever equivalent I have seen mentioned is out of stock or you are looking at around $20 bones for them I thought I would just get a bunch and learn a new skill them have extra stock.. but it’s slim pickings out there.
Last time I measured mmbf5457's with my peak I was pretty floored at how close they were, to the point that until this thread I thought I must have been misunderstanding how to match JFETs.I used four random unmatched MMBF5457's (from Tayda) for testing the XC Phase prototype. (Which explains me not catching the reversed pinout on the silkscreen)
It worked perfectly fine, in fact, surprisingly well considering I didn't bother with matching them in any way.
Thank you so much for the info (only quoting a hair to not clog up the thread - anyone else should read the reply in full!)Without changing the zener diode, you’ll want devices with tightly matched Vgs values within the range of -1V or 1.5V to -3.0V.

Quest Components (USA based) - who I've never heard of before so I can't personally vouch one way or the other - has mmbf5457s in stock w/ a MOQ of 24 that comes out to $5, which is great deal given what the prices are listed at for places out of stock. That's about what I've paid for them before the recent price increases.
ah shit didn't notice that$25 minimum order
I bought plenty of the 5457's if anyone one needs some$25 minimum order
Edit: Well it only took me 5 minutes to spend $70
These ended up being SMDI was getting through hole 2n5457 from mouser, but they're out....Tayda out too.
