Regarding the low B+ voltage, have you checked the selenium rectifiers? I believe they are located in a cage on top of the chassis near the back. They deteriorate with age and may be causing the low supply voltage.
You can replace them with silicon rectifiers, but you may have to add some series resistance to compensate for their lower voltage drop.
