The radio part is the same as for any radio of this type. Things to watch out for..
12AH8 is not the same as ECH81.
6BJ6 is also one without equivalents.
12AT6 - ditto.
19AQ5 is equivalent to HL90. Nor EL90!!
35W4 is equivalent to HY90.
These are American valve types and an american design, and the HT to the rectifier anode does not go through the transformer. Valves are in series from the auto transformer to chassis..
The clock is the usual type and will need a clean. The switch in the clock can be operated by the clock itself or just switched on. This can be shorted out if necessary, rather like that Philips one I remember.
The chassis is linked to ground via a capacitor, Put a safety type in, Y type.
The usual capacitors will need changing.
Cheers,
Steve P.

If we've always had that, why is the car boot open? You aren't smuggling in another old TV are you...?
