1951 AMC 16" TV Restoration

[Crist Rigott]

Here some more pics. I cleaned the chassis with some mild dish washing detergent. It wasn't real dirty and it cleaned up pretty well.

I checked the tubes and some are weak and some are very weak!

I then got to work on making and ID on every capacitor and resistor and comparing it with the schematic and parts list. There were some discrepancies but nothing real major. I use a small block of masking tape and mark each component. While doing this I check the schematic and parts list. I then make the document changes in red ink.

I also drew out the 2 tube configuration for the listed 6T8 tube. Besides using 2 tubes, there were a few resistors and capacitors in the chassis that weren't in the schematic. I'll update my parts lists accordingly so I get my order right.

I'll draw up the new configuration and I'll post it side-by-side with the schematics so we can see what the changes were.

Looking at your under-chassis view and the schematic, I noticed a low current selenium rectifier in the horiz yoke circuit. That's a new one on me!
I wonder what the reason was?

I wondered about that little selenium too, thinkin' maybe it was a neg.bias supply. But couldn't spy it in the schematic.
