M.O.T. inductance measurements

Hello Coilers,

I just wanted to add some more data to the information pool
about using M.O.T.'s as charging chokes.  I've taken several
measurements on a transformer removed from a fairly sizable
oven with the following results:

Stock transformer with primary open -    17.6 Henry
Stock transformer with primary shorted -  5.2 Henry
Gapped transformer (.010") secondary -    8.5 Henry

The gapped transformer had the shunts and both primary and the
filament windings removed.
