I got the above to work.

The spread sheet for the tranny does not include the
cross sectional diagram of the bobbin, and one doesn't know what
the stack height, tongue width, window length or window height is.

The datasheet for their EI-150 says each lam is .014" thick and 107
pieces are in a stack. Thats 1.498". I measured a Hammond 1628SE and its
definitely EI-150 but 2.5" thick.

Nobody would know what EI-150 is, and when I changed the various sizes,
nothing else would change.
ALL the EI data should be on the program input, and spelled out
for the dumbest of diyer or manufacturer.




No real clear details appear for the wire sizes, and possible secondary
arrangements for various Z matching.

Its very easy to have a formula calculate turn numbers based on
power and RL and the basic stuff, getting the program to think like a
skilled
and practised designer who has wound lots of OPTs is a much harder task.

When altering the current density A/mm.sq, the other numbers don't
change,
but in a real tranny design, going from 2A/sq.mm to 3A/sq.mm would
cause an enormous design change to size and turns.

They do change but you have to click inside another number window for
the update to happen. The turns stay the same but the wire size changes.


I'll let them work out the problems. Its just not good enough to attract
me.
