Matching transistor procedure

Hi,
in an old manual I found a procedure to match the transistors, maybe someone better than me can try the place!

Don't know what you are asking. That is the standard Moog transistor matcher that a lot of people use. There is an error in the schematic though. There should be a 10K resistor between the 2N3906 collector and the PNP socket emitter just like the NPN tester.

These might of interest too.

Highly recommend Ian Fritz' circuit linked above. Works well for me (and I have a little perf board with sockets and a power header kicking around for it somewhere!)

I didn't know this method, thanks!
