electrolytic cap question

[Rich12]

Hey everyone, I'm working on a set where someone has done some prior work. They bridged the selenium rectifier with silicon diodes. I got some great advice from the group on the fact that the old rectifiers were still left in circuit. Anyway I had noticed that a resistor was never added in circuit to compensate for the voltage difference. But now as I'm working through the electrolytic's I see that 2 of the electrolytic's have been grounded out of circuit? Wires to the respective positive leads have been clipped , a wire was contnected to each lead and grounded to the chasis. Is this another way to do this instead of adding a resistor? I'm trying to make some sense of this. Thanks
