What's the collector voltage? That is an extra-credit question.

John

A good 75% of the respondents would say it's close to V_b, instead of
V_e, I bet. I get emails from lots of confused people building laser
noise cancellers. Those use a diff pair, one side of which has both its
base and collector grounded, and these folks have real trouble believing
that that transistor is in normal bias.

Wonder who that'd be ?:-)

If they'd listened instead of randomly deviating from my advice their
Board (albeit one of the stingiest I've ever seen) might have hung in
there a little longer.

Nah, mostly graduate students.

Did Stheno go south?

Far as I can tell. I got paid, but others seem to have been stiffed.

I hadn't heard. I agree about the listening
though...by and large, they were one of the better ones--but at least in
their front ends, they made the fatal error of not starting with what
was known to work and then twiddling that. I've seen lots worse.
