[AMRadio] Transformer help

[Gary Schafer]

Thanks Russ & Jim.

That Is what I remember from long ago but now I am wondering if it would work ok
with a large filter cap like around 25 mf.  In the days when swinging chokes
were used a lot large values of capacitance were hard to come by.  I would not
be depending on the choke for any filtering, only voltage regulation.
Any thoughts ??
