If the pilot light were a fuse the radio wouldn't work at all.

If you're going to replace components, rather than using fault finding procedures, I suggest you start with the audio coupling capacitors C52 and C54. If these are electrically leaking they may destroy the output transformer, output valve and mains transformer.
