Bruce,
-
A pair of low value resistors, from each side of the winding
to ground make a center tap. One 10 to 20 ohm resistor
on each side to ground worked for me in a past project.
You get heat as a tradeoff.
-
You can also parallel another transformer secondary
with the main xmfr.
-
I see other have chimmed in with similar thoughts. I have
tried both methods and they work just fine.
