465B soft start?

treasurer@...
 

Is there much to be gained by powering up my 465B with a variac, lamp dimmer or similar arrangement? It popped (shorted) its 1200 ufd C4429 at power on recently. This cap does not have much head room with its 100 volt rating and 70 volts sitting on it. I'm thinking a soft power up may help prolong the life of those caps. Any thoughts or past experience from the group using this power-on approach?
