Larry, the best that I could figure is Magnetics core number
ZJ-44920-TC available from this company: www.mtldistribution.com
Send them an email to get a quote. They were in the $8.40 price
range at the time. They do have a $25 minimum order.

I think W9QQ did just that with his "commercial" kit.

I think so too....much easier to build I would think....that after
much thought RE the stack of cores I built.

This SM HV PS thing is going to really take off pretty soon. I
spoke with a commercial maker of KW amps at Dayton...sed a 300khz
SM supply for their amp is in the works. ("Don't ask/Don't tell"
any more than that.)

W5JGV has a web site that shares his efforts with
a HV SM supply. Click on "Amateur Radio", then go down
to "Project Pages". Good info there!
