Why did you do both channels for, were they both U/S?...

Not to start with but I took the transistor from the other channel to
compare them and it was duff by the time I'd got it out and I wasn't
heavy handed with it. I decided to change the compliments too while I
was at it and neither of them survived desoldering so they were
obviously all on their last legs.

Erm... in my experience transistors do not 'wear out' in a way that
means that when you desolder them they die. What failure mechanism do
you have in mind here?

Slainte,

The board has obvious signs of overheating around all 4 transistors, so
considering the P&P cost more than the replacements it made sense to swap
them all out.
