The 650vct will give 325 x .9 (minus resistive losses) and the the 300vct will give 150 x .9 (minus resistive losses) with full wave rectification and a choke input filter.Tre'

Actually, I do believe you'll get the voltages quoted assuming FW/CT, cap input filter and ignore rectifier and other losses. (650/2)*1.414~460. He combined steps in the basic math.
"He combined steps in the basic math."
I see that now.
But it's a choke input filter.
BTW I fixed my math.
Half of the end to end voltage times .9, minus losses.

I believe the OP specified a choke input PS. 325Vrms times 0.9 equals about 290Vdc. Add the losses in the second choke and you are close to 260V. My question is: If you are using CCS fed shunt reg. why the second LC filter?

L input, I see that now. That's why I state my assumptions...even if I'm wrong.
