Another few hours on this set today. The local oscillator does run on long wave but not very well, only -0.2v on the grid and it stops at the low frequency end whereas on medium and short waves there is -2v.
I've checked everything on the wave change switch and all the coils and found nothing so I am assuming that because the ferrite pots are broken on the long wave oscillator transformer coils the Q is so low that it stops it oscillating. So that would seem to be an impasse, finding another for this rare set is not likely. I'll pretend it is an export model!
