Fear Of Selenium Rectifiers (Rectiphobia)

It's Friday, time for some beer!!!

Ok here's an update on my old '53 Philco. I still haven't plugged her in. I have obtained a Variac via Cragslist, it's an old one but it looks ok. So I'm all set hopefully for a careful power-up (more questions on that another time) when I get a few more issues straightened out.

Last night I hooked up the REM CRT Tester/Rejuvenator box that I scored at the flea market ($4.00) and ran through some tests... as far as I could tell, the picture tube isn't toast. The test meters were right about in the middle, definitely not in the red but not in the like new range either. I did not try the "Rejuvenate" function yet, I think I'll wait until I know more before I go zapping it. I was pretty glad that nothing blew up in my face!

Now.. the selenium rectifiers. There are two of them on the sweep chassis. I know I have to use silicon diodes, and I guess add resistors to the circuit etc etc - the more I read about it, the more the selenium rectifiers in my brain heat up. If anybody out there has already done this on a Golden Grid and could point me on the right path to success, i.e. parts needed, wiring diagrams, pictures, anything - I would be eternally grateful. Everyone here has been just great!


Time for pizza!!!!
