From what I read, I figure that if there was a short the Q would be
lowered enough that I wouldn't get any ringing... even in circuit.
However, with that said, since my ringing is drastically *lower* than I
expect (I thought there should be a 300V oscillation on the collector
with a 36V supply), something is dragging this down.... so I think it is
simply ringing at the expense of excessive current because the Q *is* lower.
I will try the low voltage out of circuit ring test today and report
back... with the low amounts of current, Im guessing that I will not get
a *good* ring out of it.
