Lightbulb Re: Roberts RT7 - problem

This is my first ever post here, so be gentle with me, and I'm not familiar with this radio, but looking at the circuit diagram above isn't it possible that a break in the track to R30 could be sending the output stage unstable, and all that heat is actually a result of it oscillating violently?

That's my hunch, anyway. I'd be interested to know what the learned company here thinks.
