That's great news! You could easily buck regulate the +15
down for a filament supply as well.

I've seen transformers with seperate primary and secondary
windings. If a company is building s standard product line
with various outputs they'll sometimes do that. Although it
usually increases the leakage inductance so that's the down
side. Sometimes the output inductor and transformer can be
combined.

I hope this goes though. I keep getting error 441 so I sent
you an email regarding your last post.

This is just way to cool. I took a 500watt Lambmda 15 volt switcher I
had used to power a solidstate amp and wound another secondary on the
transformer. I lost count of the numer of turns, maybe 100, but
after filtering and rectifying im getting about 450 volts and it has
been running since about 9:30 AM 3hrs putting out 150mA.

These transformers look a little wierd They seem to be two sepated
coils fastened together on a frame. It looks like you could take the
secondary coil off and replace it if you wanted to.
Grumpy , are you familar with this.
