Oh boy! Time to reassemble some parts....
It has been a while since the shop saw my shadow. But I am back at it now that the weather has warmed a bit. Oh I was in now and again to touch up the gold lettering.
I will fill this table in as the radio goes back together.
This is the reassembled fully restored radio. After 60 hours of labor and a few parts this radio plays and sounds great.
Every nut, screw, bolt, washer, screw, latch, hinge, escutcheon, lamp socket, insulating fabric has been cleaned, polished and buffed to a shine. The cabinet received sanding sealer and many coats of clear and toning lacquer. The lacquer is still drying. The cabinet can be past wax polished after a few good weeks or months so all the coats dry hard.
The second RF Bi-nocular coil (center) started to arc from a ground rivet to the coil wire carrying B+ 90 volts. I removed a few turns of wire from where the rivet was contacting the wire, coated the wire with lacquer and rewound the wire back onto the form. I also snuggled the wires up and away from the grounded rivet creating an insulating air gap. Again lacquer was applied to the bottom three turns of the offending coil and form base. Once a day of drying has occurred once again B+ will be applied to the radio and tested.
Not bad for a radio manufactured in the 1920's.
