Is there a reliable seller for these, or do I need to investigate substitution options?
Ricardus said:I'm pretty sure NTE has some in stock. I bought a few last year:

I bought some last year to have as backups. I still had some NOS Fairchilds so I used those in my builds, but the NTEs tested out with good quality.

I'm sorry to say that sadly, Bernard Loffet has passed away. His wife informed me of this , and told me she has no intention nor the competency to pick up where he left off.
RuudNL said:It is probably because Neumann used the 2N3819 in a lot of microphones.
By the way: I got a batch of 2N3819 FETs from ebay, there is even an 'F' on the FET (Fairchild?).
They came from China...
Fake or not fake, they are excellent! Can be biased correctly and produce very little noise. (Lower noise than other brands.)
So not every Chinese seller is selling fake products!

It's much more likely (imho) that there wasn't all that much to choose from at the time, in the first place ;D But what do i know? :
Might also be that it's what's usually called for in the BOM of a lot of DIY projects that were written up before the 2N3819 became special order. So you see it on the list and think it's what you need to use.RuudNL said:It is probably because Neumann used the 2N3819 in a lot of microphones.
