I never touched the selenium rectifier, as I'm unaware of the correct replacement parts, although I have used a 1N4007 before and never had any issues (I never used a resistor with the 1N4007 Diode, just did a straight drop-in of the 1N4007 in the radio and it seemed to work fine.) as for the tubes, I did replace the 12AT7 because the original (and yes I do mean the original Zenith branded 12AT7 that was from when the radio was made) had gone to air at some point as the getter was non-existent and white colored, I tested all of the rest of the tubes and they tested like brand new yet including the 19T8 which was a GE branded replacement from 1963 as for the 6AB4 and the 6BJ6 they were the original Zenith branded tubes from 1960 and they tested like new yet according to my Sencore Mighty Mite VII tube Tester, and the 35C5 was an RCA replacement from the 1970s because it had the Block Lettered RCA emblem on it. As for the Alignment goes, I was attempting an Alignment job and I was working on the 3rd AM IF can and my diddle stick broke off on me inside the IF Adjustment slug and I have no way to get the broken diddle stick out of the IF can, does anyone here have any ideas of how to go about removing the broken diddle stick from the IF can adjustment slug?
