I've seen transformers with seperate primary and secondary

with various outputs they'll sometimes do that. *Although it
usually increases the leakage inductance so that's the down

combined.

I hope this goes though. *I keep getting error 441 so I sent

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.

Well, The transformer winding doesn separate the way I thoufgt they
did. there is a pretty good sized gap betwen them,1/8" and it seems
one is a choke. I was confused because I have a couple of old scrap
power supplies that are made as previously described. They appeared to
be the same so I made a very incorrect assumption.
