Several years ago I remember buying an Allied Electric branded power transformer similar to this one:
But if I recall correctly the unit I bought was somewhat smaller; the primary had no center tap and the filament winding was rated for just 300 mA. It doesn't seem to be on their site anymore. Does anyone make a similar product?
At these power levels I'm wondering if it might be easier and cheaper to just use a switcher for B+.

Try Edcor too.
Or if you had an automotive application in mind,

Nice use of the "Forrest Mims" oscillator topology!

Hmm, hadn't thought of that. I pieced that together from scratch, but I suppose some of the feedback bits are reminiscient. It's not really a multivibrator though, more like a monostable with a variably leaky re-trigger.
Predecessors used feedback from the output transistor (gate or drain), but as this varies with supply and load voltage, I try to avoid doing that. Still, comparable performance and behavior (current mode control, no feedback winding required) from four transistors wasn't too bad either.
