for folks that are interested in more extensive jfet matching than idss only and have a scope and function generator (which of course, you can also diy), just sharing a link that i haven't found posted elsewhere on the site (however, i did notice that EUVL makes mention of the technique in at least one of his posts).

Nice article..... I too had a TEK 576.... took up a lot of bench real-estate. I donated it to a local 2 year tech school. I replaced it with a similar new product made in China... it also lets you see two devices at the same time on the CRT (-yes, a real CRT) screen over-lapped for matching. Smaller, lighter. And the old TEK adapters work with it!
