I've never had problems with the transformer models that come with 99se - I
use them all the time.

(ok, that's not exactly true, they can be a pig, but do work if you use them
right.)

I usually use the dual primary, dual secondary and join the middles
together.

or you can use two separate transformers and put a (.K) I think somewhere in
the drawing as text to
indicate a coupling coefficient between the transformers.

G'day,

Does anyone have a Protel Spice model of a transformer with a centre tapped
primary?
The models that come with 99SE have errors and are not bidirectional.

Thanks,
DG
