Hi David,
Updated 03/24/2023
This is a neat radio, between the push pull output and the inductive tuning (common for car radios, very rare for a "home" radio), shortwave bands, etc.
If by "rectifier terminals you mean the rectifier secondary to the plates of rectifier (Pins 4 and 6), this should be a lot more than 110V. It should be about 700V between the legs and 350V between either leg and center tap (all of this +/- 50 - 100V). If you meant the record player chassis, what you are measuring is the normal current through the AC Line capacitors, C30 and C31.
Disconnecting the rectifier plate and filament windings and the filament winding to the other tubes is usually unnecessary. Merely pull the rectifier and the radio is safe to power up.
For this radio, it is not necessary to "stuff" caps (hollowing out the old ones and installing the replacement caps inside). For the electrolytics, merely install a terminal strip and move the wires from the old can to the new caps. Replace all other paper caps. However, because some radios are unique (this is unique) and valuable (I don't know how collectable this is; it is a great radio, but it is not an EH Scott, a Zenith Stratosphere, etc.)
Definitely either replace or merely remove the caps that goes from each leg of the power line to the chassis before powering up. You will get a "tickle" if the caps are good and a flat out shock if either or both of the caps are bad. These caps filter AC Line interference from the radio. They are not critical, therefore they can be removed, but they should eventually be replaced appropriate "safety" caps.
As for the turntable, I don't know if the Voice of Music website will have a capstan wheel or tire. You might try to take the wheel to a hardware store to see if they have an O ring that will fit. Not perfect but better than nothing. Regarding the cartridge, that one takes either old Victor needles or a replacement with a more permanent sapphire needle. I prefer to put in a more modern ceramic cartridge, but you want one that has the option of a 78RPM needle, as 78RPM needles are bigger in diameter than LP styli. Playing 78s on a LP (33 1/3 RPM) stylus will heavily damage both the record and stylus.
The motor wiring can be resolved by splicing in new wire using heat shrink tubing.
