Benny-

Rather than copy from the Sams part list, I recommend making your own list from what is actually on the chassis itself. This is for several reasons:

-Many TVs went through production changes, so the Photofact list may not match exactly. You want to replace the parts in YOUR particular set. (Also, some Sams manuals have had mistakes; you should match what you have, not what the list says typically.
-Actually checking every part in your set is good hands-on experience with reading values and understanding different part types.
-Physically checking every part of the chassis will ensure you don't miss any parts.
-The close inspection will also help you to find any parts that have been replaced in the past; the more hands-on you are, the easier it will be to identify repaired areas or parts that don't match up well with the rest of the chassis. Repaired areas should be compared to the schematic; if you find things that don't match, you can always ask here for help from other members.

Regarding resistors, the high-value ones are the most likely to change, so check the yellow-third-stripe and green-third-stripe ones (or blue if you have any), since those are the ones over 100,000 ohms.

Grid-fed video means the output of the video amplifier circuits goes to the first grid on the picture tube; cathode-fed means the video amp feeds the cathode of the CRT. You should be able to tell which you have by looking at the schematic diagram. I do not remember learning that either was better than the other.
