Ok so when bought the Emors mains transformer was cooked I've replaced it we have HT we have heaters all good I had some spectacular bother with the socket of the 6q7 that's now resolved. When turned on I get him not a deep rumbling smoothing cap hum more of a record player hum if that makes sense. This appears to be an early Emor it has various differences from the version I have a schematic for. Now when I bought this thing Mr bridge had been in the volume control wiring had been chopped about I have sorted that and one of the valves the 6k8 had had a length of wire soldered to it and shoved down the chrome tube assumedly as some sort of aerial I'm at a loss as to where to prod .

Ok an update to that I now have signal but very week a screwdriver touching the top cap of the 6k8 improves this considerably this being the valve that previously had a wire soldered on to it ( tried three other 6k8s )

Clean the waveband switch. I would then try an RF alignment if you have a signal generator.

Waveband switch is spotless it doesn't seem like alignment I think it's time it paid a visit to eBay I have a multitude of Philips to wade through including my 930a
