What's the biggest inductor, the most Henries, that you know of? I
seem to recall some audio transformer that was something like 100 H.

There some pretty big ones in the nearby substation but I can't get near

They probably wouldn't state the inductance.
 
One outfit that makes utility transformer test sets say that their
gadgets measure up to 10H. I was hoping to find something outrageous.
 
Hammond makes a 200H inductor. It is NOT good for 30 amps!

Inductors are the worst parts that we can buy. I can wave off the
imperfections in my inductor simulators by noting how bad real
inductors are.

Trying to squish everything into a very small package must be murder
on the Q.
