As a tap off the full secondary, you could expect to be able to draw a fair amount of current. Recommended? Not.

My bad .. that's all good. It's possible but unnecessary to pull 100x more current than required from the bias tap. Natural result of tapping into a fairly high current winding. Nothing to worry about, but also not concern in design of the transformer either.

Sorry .. Ian
