Looks like I'll be rebuilding this one completely.

It looks like they did neat work,but put the wrong value resistors in.
As Mike pointed out, they were done as a specific mod and it was good work. I'll be bringing it back to the original circuit with equally good soldering skills!
Mike rebuilt my Mc240 and it is beyond improved and wonderful sounding.He is a great guy to deal with and really knows his tube electronics.
So I swapped out the dozen hi value resistors for stock values and all of the readings fell into spec +/- 10%. The carbon comps that remain will be replaced with CF & MF 1% and it should be good to go.
It's Alive! All is well in MC240 land. Voltages are within 10%. A full resistor swap should have it right on spec. It even sounds good!
Thanks for the help.
