I have got all the parts together this Sunday afternoon...
Found the #4 internal cat screws too.
The meter face is deliberately dark so not to be intrusive into the living room, works...
Save the old cartridge resistor. It can be re-wound to a lower value for another DC Radiola.
For the volume rheostat, the old "track" for the wiper may not align and be "scratchy", so use 400 paper bit, under wiper and stroke just a couple of times. Too much removed will increase the overall resistance and weaken the resistance wire. Clean the rotating contact under the hub of the wiper too...
Try to mount the caps onto the frame, so they come out with the radio and not be screwed to the cabinet. A help when servicing the chassis on the bench. Locate the terminals out of the way less some errant hand contact the B+... Stay clear of the RF and oscillator coils... If, you see a shadow and screw holes in the cabinet that agree with the caps then mount to cabinet and put lugs on leads to reach the terminal strip connections for B- and the B+'s. There may be leads within the battery harness for that purpose, taped off. Often, the three wires for the protective lamp are joined and taped off...
The OEM finish on the caps is a bitumen (tar) tinted lacquer...
I'll pack these and try to post tomorrow.
Regards,
Chas
