Quick update on this repair:?
I fitted a replacement 5351 and replaced IC501 and IC502. The radio now receives well so I'm happy that the replacement 5351 is functioning. It's only putting out about half a watt so I'll wait till my replacement for IC503 arrives before testing further. I've not checked with the scope to see if IC503 is actually faulty but it's the next suspect in the chain so I'll swap it out anyway as I'm quite enjoying the challenge of the SMD soldering. To be honest, I really wasn't expecting the 5351 to go in so easily ?... Onwards (slowly) and upwards...
