Had a look at this. The radio was full of dust and gum leaves. The dial cord had disintegrated, fragments being found in the dust. The dial light was blown.

Removed and cleaned the valves. Cleaned away the dust, which revealed the valve types stamped on the chassis. They matched the valves supplied. Types are 6A8G, 6U7G, 6B6G, 6V6GT, 5Y3GT.

Replaced the paper caps, and the black unmarked lozenge-shaped caps, some of which had partially melted. While doing this, noticed the plate resistor to the 6B6G looked rather scrappy, it was found to be open so was replaced.

Although I had never done it before, decided to power up with a 60 watt globe in series with the mains. Lucky, because the first filter cap was almost shorted, giving only 20 volts of HT. Replaced this. Also replaced the dial light.

Now, the radio worked, with good reception. Amazingly, the 6U7G behaved itself without its shield, but I put it back on anyway.

Remaining problems:

- Needs new dial cord
- The lamp only works when it feels like it
- Dial needs cleaning
- Tuning capacitor shorts out in a couple of spots at the low end
