Quick update, we have SW!
Inspected panel 1 and found R52 open circuit, currently don't have a 15k resistor on hand but have a rheostat so that was adjusted to 15k and soldered in and not only got all voltages on the SW H.F Amp but also managed to find 3 SW stations, a french one(?), Radio 5 and Radio Caroline?
So now confirmed all bands work I can start recapping.
Voltages across couple valves that I've checked also went down and are a bit closer to what they suppose to be.
