I don't have a lead on where you can find a mod transformer, but as far
as chokes are concerned, you don't -have- to have just *one* choke.. you
can string 5 10Hy @ a half an amp chokes in series, and get 50Hy's.
I had to resort to the same thing, when building my reactor. Never
could find a single 50 or 60Hy choke at a half-amp... I now have 120Hy @
400mA, but had to put 6 (or 8?) of 'em in series to get where I am.
