Selenium Rectifier Question

[Rich12]

I'm restoring a 1949 Emerson TV that has had some prior work done. As you can see from the pics 4 silicon diodes have been wired in. I can only pick up writing on one it appears to be an R170 which I believe is 2.5 amps / 1,000 volts. The soldering joints and connections look very well done. My concern is that they appear to connect in circuit with the existing 2 rectifiers instead of being detached? Also there is no additional resistor on the lines to the electrolytic's. I don't want to break it if doesn't need to be fixed? I'm a long way from putting this on a viac, I still need to replace numerous paper caps, electrolytic's and at least a couple tubes. Comments and suggestions are appreciated. Thanks!
