[Amps] Transformer spec's for linear amplifier

[GGLL]

	Having the need of a 2500VDC @ 350 mA maximum current power supply, and
planning to use a full wave voltage doubler, how can I establish the correct
current rating for the transformer?. It should be nearly 930 VAC and exactly
700 mA of current, or can I reduce somewhat its current rating (taking in care
amateur, CW/SSB use, also AM at reduced carrier) so as not to expend more $$
than really needed?.
Thanks in advance
