Matching jfets for beginners? (for the schematics-analphabet)

[myleftear]

Hi friends

Since I'm confident that I won't give up on DIY, I need to understand such stuff.
But being a "schematics-first-grader", I'm really having difficulties on understanding the resources about how to measure/match jets (etc).

Mr Pass's article (passdiy, here) on this is very easy to read, but—schematics only, aargh! (the others just being—gradually—more complicated)

So, if a friendly One please could post a reproducible construction (a comprehensible Foto?) of one of these nifty little helpers?

I've been reading through almost every website, watching countless utubes, hoping to finally find an easy, reliable measure-thingie (perfboard) I could clone, with a manual... If there'd be a schematic, fine (climb the learning-curve)

Thanks many times!
david

That page covers MOSFETs not JFETs.

You really do have to start from kindergarten. Nobody is going to do the basics for you.

If you want to get a good foundation - suggest working through "The Art of Electronics" it's available for free as an ebook in the 3rd edition and it starts at the beginning. All the best.

I plotted "jfet matching" in search field here and got alot of similar threads, jfets behave different, I'm sure you'll find some interesting stuff, I did.
Here's a link to YouTube with jfet basics

Thank you, amplitude!

Yes, I saw (and read) a lot of them. It's the smoking head phenomenon, and I try to find a post / image that "says everything" (which isn't possible, I know).
Just the illustration of what a schematic looks like in real life...

But... I probably have to put a few projects at risk myself

Hi PRR

Thanks, I know.
I actually wasn't asking to "get fed", I was actually asking for a different/simpler way to look at things so that I can do it myself.
Sometimes I just don't see it because I don't know how to look...

(I seem to be still in the stage of seeing through touching, haha—another way of saying 'kindergarten', maybe?)
