Finished up all the other voltages and they are within expected ranges.  Last measurement - on H4 and H7 read  minus 3.1.  H2  & H5 read plus 3.1  ( p 61 ).  Don't know if the +/- in the manual means that or not.

Yes, you have a total of 6.2V there, which is what's desired to heat the 6.3V heater on the tube.
