Thanks for the tip. I found the fault at the grid of the 2nd stage. That bare wire should be soldered to the coil lug next to it
I made the repair and fired it up again. It's much louder now and the volume control definitely has an effect.
I can't cut the volume down to zero for strong local stations though.
Also if I turn the volume up loud, the set starts oscillating then cuts out altogether.
I've never operated a set like this before so I'm not sure if that's normal or I should keep tinkering.
There's an RF compensating I can fiddle with and I could replace the original caps on the RF coils and detector with modern micas
