I wouldn't worry about it. The capacitor can has been 'conditioned' from new to work at that voltage and will probably out live you. I had exactly the same issue with an amplifier in a record player with an EZ80 valve rectifier and a smoothing can rated at 350 volts continuous, which had an HT of 400 volts fully loaded, the can capacitor had a surge voltage rating of 425 volts, though. I queried it at the time, but it doesn't seem to have caused any problems since around 1960 when the unit was made. There's a forum thread regarding it a couple or three years back - picture of amplifier below where you can just see the ratings on the can:-
