I've been working on a circuit where I used the LM3046 and decided I wanted to try it out using regular old transistors, so I needed to match some. I found this doc on line describing a pretty slick technique. I tried it out and it seems to have worked well. Here's the link https://home.comcast.net/~ijfritz/MiscProj/transmat001.pdf (https://home.comcast.net/~ijfritz/MiscProj/transmat001.pdf). So, I was wondering if anyone here had used this process or had suggestions for different methods?
