Woohoo!! It lives!
Just sitting in Baldock Services as I post this 
Anyway, can you guess what this is?
Oooo Mike, that'll be my 22" Philips G11 
"And here are the results of the Swiss jury".... err wrong show, this is the "Fortnight Saga", more commonly known as the 9000 ways to go mad show!
The transistor mappings for the mute fault, they look all over the shop

Well spotted about the heatsink being strapped to the emitter Graham. If it had been at earth potential as is the norm the fault would have been less mystifying and fairly obvious but that's easy to say with hindsight, it had to be something off the wall for those readings.
The mute fault and the no remote operation should be very straight forward now, there are very few components that can cause loss of the 15v rail. I presume the 24v supply is present at one end of R80?

Before reading John's post I had found the 24V supply was missing from the tuner board via 44/1, replaced the pin and now sound is restored.
The End............Phew!

Is it the end, do the remote functions work? Just because you've seen that "cherry" appear on rack
John.
A jolly good soak test now with the back on, well done for your persistence.

The End............Phew!
That's "Murrayed" it.... 
As in Murray Walker... "Of course, the one advantage of being in first place is that you have a completely clear windscreen and can see exactly where......" [CRUNCH] as the car ploughs into the earthen bank......."you're going!".

At the end of this saga, all I can say, Chris is "wow" 
Now you see why I wish to steer clear of complicated sets, like this, as much as is humanly possible! Especially complex transistor designs!
Not only did I have luck finding a back for my Baird 8724 I managed to find a stand on E-bay which was the perfect width, depth and colour match for my 1975 Multibroadcast 773 ( Thorn 9000) I now looks excellent even if I do say so myself.

Splendid result, looks good in its setting 
Brilliant...
All you need now is a GPO "Trimphone" and an Antiference set top yagi (aerial), one of those cream and gold ones..
