Thanks Jon. In my case even when the outputs are at
0V, I can see the that the output transformer is producing outputs, if that is true would
that confirm that startup is not the issue here?
Well, maybe. If it is a steady ~20 KHz on the transformer,
the startup circuit is OK. If it is an intermittent pulsing
a few times a second, then the startup is "trying" but the
converter is failing to power itself. (Or the crowbar is
killing it.)
