Okay, well after 2 months waiting for a tube tester, multi meter, and test light, I started back on this Philco Transitone set.
I was able to determine that 3 tubes were bad, replaced them, but still no light.
I took everything apart again, double checked my work, inspected more wires, everything looked good, so I put it back together, said an earnest prayer, now there's a nice bright screen!
I have no Idea what I did, so I will thank God!
It still has some lines, sometimes looks like a film negative when fine tuning it, and has a buzzing sound, the photo fact said to adjust the IF (A9) at the top of the chassis to get rid of the buzz, but the schematic shows that (A9) is actually in the middle of the chassis, a small hole just above the horizontal output tube.
I tried putting a small screwdriver inside of it, (I think it goes inside one of the aluminum rectangular cans), but I don't feel anything to adjust.
Anyone know how to adjust the IF ??
