The schematic does call for a 1/2w resistor, which is what's in there.
The I have the sams 70-7 and it is actually the schematic for the 730tv which is very close but it doesn't have the audio amp on the tv chassis, and has a few other small differences. Just last night I found a copy of the original service information for the 721ts here:
http://www.njarc.org/manuals.htm I ordered all my capacitors based on the parts list in the sams and then later found out I didn't have all the ones I needed.
The power supply is odd in this set with that -85v supply and not just tying all the filter caps to ground, it makes figuring out how to put the new electrolytics under the chassis a bit more difficult.
I've been closely following that Admiral thread, strange tv problem, I've learned some interesting stuff reading that.
