Finally - some time to work on the radio.
I started the day by looking again at the cabinet. I gave the interior a really thorough clean/damp dusting to remove the last hints of rodent occupation. In the process, I found some additional areas that were separating, so applied glue and they are clamped up for the night. Then I removed the sound board to inspect the cloth, and to attend to the "fringe" trim that runs above it. This is a ribbed/castellated section of moulding that was loose and split from the batten which holds it. That was dismantled and reassembled carefully with glue.
Well, this is really the electronic section, so I made progress here. A 4 wire "umbilical" to run between speaker and chassis was twisted together. I fitted the transformer to the speaker basket, and completed wiring of the field and voice coils, and the umbilical and its plug. That is all ready to go. Next I need to make a checklist of final items. This will include:
1) Replace dial mechanism and shadow meter.
2) Complete chassis wiring of the 2 power supply caps.
3) Replace the 10 K wirewound pot for the interstation noise control. The original is bad.
4) Solder top cap connectors to the new flying leads for RF valves
5) Re secure the large wirewound resistor to the chassis.
We are getting there!
Cheers

I don't hold with furniture that talks.
