Maximum Capacitance for Damper Diodes

In a voltage doubler supply using damper diodes with 400mA continuous rating and 2500mA peak rating, what is the maximum safe cap size to use as the cap side of the doubler. I used (2) 600uF 330V (465VDC output)and just exploded a rectifier tube.

Do I assume each cap is a resistor with impedance as derived by the 1/(2*pi*Hz*uF) formula, then figure the current using Ohm's Law? doesn't seem right due to slow warm up of the tube. If it's right, then about 28uF is maximum for each of the two doubler caps.
