A tale of two simulators

I have put this schematic through LTSPice as well as the Duncan Amps PSU Simulator - and got very different results for the output voltage. The results from the Duncan Amps simulator are more believable with the resulting voltage being close to 1.414 * AC Voltage. The results using LTSpice project an output voltage of 1 * AC Voltage - no matter how I tweak the values of the inductors, the voltage at R2 on the diagram hovers stubburnly at 250 VDC.
The experts on this forum are free to send me to the back of the class for missing something obvious, but nevertheless I would be grateful for some advice on where I have made an error.
Cheers, and wishing you all a Happy New Year
