But there does not seem to be a search function at the Engineer's Garage web site.
Does anybody know where this circuit is posted so I can learn more about it?
Hello Allen,
If you're after an "In circuit Transistor Tester" in general, might I
suggest you try Silicon Chip magazine in Australia.
Their September 1993 issue has a project for that very thing.
If you live in Australia you can purchase the issue and have it delivered.
If not, you can buy the online copy and view it in your browser.
They give a full explanation of it's workings.
I hope the above helps you in your search.
Regards,
Relayer
