[AMRadio] Capacitators needed

[Gary Schafer]

In working on my 4-400 amp I finally got to the point of trying the high
voltage supply. I used a variac and could not crank it up very high at
all without the transformer complaining. I put the clamp on ammeter on
the ac line and saw why. The ac current rose rapidly.
Pulled out the filter caps and found a shunt resistor open. Worst
thoughts came true. Bad filter caps. Took them all off the board. Every
one is shorted and a couple of more of the 10k 20 watt shunt resistors
are open.

So... I am in need of some filter caps.  What is in there now is 9 each
240 MFD @ 450 volts. They have screw terminals made by mallory. Does
anyone have any capacitors like that or possibly an oil filled capacitor
of around 25 MFD at 4000 volts or so ?
I am open to any other type that I can make fit in the space available.

Thanks
