If so, you should know what to do.

Thanks to everyone. I have the problem resolved. It was a combination of things, filter caps, 227 AF tube and a problem in the 224 detector circuit. Also a good cleaning of all the tube sockets helped. The radio is repaired now and working. By the way, my old 260VOM and my newer Flukle digital meter both read very close to the same voltages.
