Oh dear!

Ah... so that smell wasn't just my housemate burning toast...

I wonder if the deletion of the 2K2/47p step network has led to HF instability? The 2k2 is still present, but doing nothing as the 47p is missing.

Out of interest, is there any way, short of massive investigations, to make an educated guess as to what actually failed and started the carnage?

That's easy... an output transistor! Why did it fail? We'll never know...

Well It's now getting NCC220 modules and a Vellemen protection unit fitted.
