Gosh, I hope I did this right!

Back to work on the '53 Philco, I finally tackled the selenium rectifier replacement and even if I screwed it up it was fun and it sure looks purty.

I really am not totally sure if I used exactly the correct diode/resistor combination, but I *think* I'm in the ballpark anyway, based on quite a bit of reading up on it first. I used an IN4007 1A, 1000 volt diode and a 2 watt, 47 ohm resistor for each of the two rectifier replacement assemblies, and I wired them in properly as far as I can tell. It's hard to believe that these little doo-hickeys can adequately replace those big blue spaceship looking thingies.

Probably this weekend I'm gonna toss it loosely together and try a low voltage power up to see if I get any signs of life. If I do then I'll start on the capacitors!
