You're gonna have to replace more than one electrolytic, I reckon! If you want to preserve appearancees, you can take the slenium recitfier apart and restuff it with diodes say 1N4007's if you can get them, they're almost obsolete now! Otherwise just mount the diodes on a tagstrip. Also you will need a series resistor say 47ohms 2watts as the selenium rectifier is not as 'good' as the diodes. 250v rating is probably not enough if thats the PIV (peak inverse voltage) rating, perhaps that's the "X800".
