Thank you, Morzh and MrFixr55. I now have correct B+ voltage. I was measuring the voltage when powering the set through a dim bulb. When I power it directly, b+ is correct. Also, shortly after I posted my question, I noticed that the schematic lists what the b voltage should be at the tubes. Oops. Yes, center tap of the hv secondary of the power transformer is not directly grounded to the chassis.
