This might help someone else...

The heater indicator bulb had also blown, small bayonet type just to the right of the tuning dial and suffice to say a pig to get to it and replace. Anyway I replaced it with something I had to hand a simple car side and tail bulb. RU233 12V 4W BA9 cost 60p. The fun bit was getting the old one out and replacing the new.

1/4" bore rubber hose (like the sort used in school science labs with a Bunsen burner), snug fit over the new bulb allowing it to be fitted, once locked into position the rubber tube can be rotated off.
