Controversy on Transistor Testing: Can't be both!

Hey rhb! You are brilliant. Thanks for sharing.
rhb:
Sorry. I conflated this with another thread. One glass of wine to many.

No harm...do I win the prize for the C-E answer?
rhb:
You're the 3rd person to know how to tell them apart, but using the reverse breakdown is a new one on me. So yes. You certainly do. I learned another way to do it.
Learning something new always makes my day. At least if it isn't a "do do that again" something new.
Clearly I'm going to have to build an octopus. I've known about them since the mid-70's but never got around to making one.

Last night I was having dinner with a guy who used to work for me. I asked him the question. He had the same answer as I. Well...we are both IC designers for 40 years, so we think beyond the schematic (junctions, doping level, parasitics, etc.). So, it is not surprising that we would get the same answer.
I was in high school when I built the octopus I have now from the schematic in the earlier post. That pretty much gives away my age.
