Hi first time poster.
I am restoring a '73 Minimoog synthesizer and it requires a complimentary pair (in this case 2N3904/2N3906).
I noticed in a previous post that a test circuit designed by Elvee might be the answer.
The attached is the circuit from the Minimoog service manual.
In note (4) the request is that the PNP Vbe is 10-20mV lower than the NPN at 200mA.
I'm not an engineer, but I think at that current it would deep fry the BJT's or cause thermal problems in the matching process.
Any help appreciated.

Hi, what happened to the post I submitted.
Sorry for being a PITA.
How do I go about reposting in solid state,
FYI, I use Kaspersky to protect me and it considered your post as a scam----go figure.
Thanks for your patience, what buttons do I press to make the magic happen.
