I think I used wrong inductance on first sim
Hammond 726 120v-1790vct
120-895+895 transformer is 1:7.5+7.5 voltage ratio or 1:56+56 inductance ratio (rounded up for simplicity)
56*30h primary = 1680H secondary
(I learned that from Dave Slagle)
I didn't round the figures above so 1668H is closer to not rounding off.
The schematic outputs at 844volts, Hammond site says V*.45 (1790*.45=805) for Full Wave Bridge without the cap so it seems accurate to me. Sims just under 800v without the cap input.
