I have one of these gems too.  My AC line voltage runs around 124 to 125V.  I rebuilt the cadohm with a 75 ohm and two 910 ohm 5 watt resistors.  I used a little JB weld to attach the resistors. to the cadohm shell.  That gives me B+ 84V on the 3Q5 screen (pin 4) and 8.6V on the filaments.  Testing with 110VAC gives 73V B+ and 7.3V on the filaments, and the radio plays well.

I also added a 8.7V 5 watt zener between the 9V end of the cadohm and ground to protect the filaments from any voltage surges.  Probably overkill, but who knows.

I replaced my leather handle with 1 inch wide chestnut colored leather strap I bought off of Amazon.  Same thickness as the original handle, and surprisingly nice leather.  I used a Dremel carving bit to slightly elongate the holes so the strap can pull away slightly when the radio is picked up.  Take care not to make the slots too long or they will show when the handle is lifted.
