When testing resistors, it often happens that the ends of the resistor are connected through some other path in the circuit, and you get a lower reading than you should. You can sometimes look at the schematic and work out what that should be, but often it's just easier to remove one end of the resistor from the circuit and then test it that way.
But if the set works normally before it warms up and the problem is caused by a bad resistor, it won't test that bad when it's cold.

Thanks for the tip! Just tried that and the resistors do check in spec so time to replace some more caps, I just did anoter 4 now
also do you know what voltage the disc caps would be? It says the value on the one but not the voltage, I figured I'll replace those being there directly connected to the horizontal section, I also measured the high-voltage with the HV Probe on my sencore tester, according to the setup booklet for the CRT it has (23EYP4) it is supposed to be running at 25Kv but it's only reading around 19kv but I somewhat thought 25 KV seems a little high for a B&W set?, Also I'm not sure if we're still making the trip down there next month or not, if worse comes to worse are you going to the September ETF? If so maybe you could bring them there and I could bring the RCA sportabout for you there as well.
