Hi John, Paul, Nolan,

Nolan, hope you don't mind if we play around with the numbers. Also, can
you verify something. Is your
secondary 15" high wound with 28 awg with a winding length of 12.75"? If
so, I used 15" previous, so
all the numbers will be off, but it's a good exersize anyway.

John, on the helix -3.000 value, I used a wrong input. However, I see what
your getting at.

Paul, Acmi appears to not equate correctly using Acmi's own inductances and
K. I think John is correct
here. I will go back and check my inputs to see if I made some error. Maybe
you can take a look at the
input file I sent.

I'm pretty sure Nolan's secondary is 12.75" high and not 15". I'll go back
through these today with
this new secondary length. If you can check with the 15" length anyway, I
think all the other inputs
were correct.

Take care,
Bart
