Assuming the SAMS numbers are not typos, I would expect within +/-20% or maybe 25% worst case (trying to allow for parts tolerances, tube variations, tolerance of your meter, etc.). But also watch out for circuits that have variable resistance, like contrast or brightness controls. If SAMS tells you how they are to be set, do that, but if not, vary them and see if you can get the specified reading at some setting. For example, if the video detector output p-p is wrong, is it because of AGC adjustment?
