Another Mk I TR82C.

[Robert Darwent]

If selecting LW stops the oscillator and yet the switching, LW coils and LW cap/trimmers appear to be OK - then the only things left are TR1 itself and L7,L8. Do the three voltages on the diagram for TR1 roughly agree with readings taken in your set Joe? (B=1.0V, C=6.4V, E=1.1V)

I'm wondering if this is a weird fault with the OC44?
