Well, I got them fitted, and the right way round. Put it all back together and in the case.
Only a little PP3 to hand, and I got a pop from the speaker. The transformer no longer runs hot, though I got nothing on Long wave. Flipped over to Medium, and picked up a couple of stations, but soon lost them and got nothing. Checked the battery voltage and it was down to 7.4, so suspect I need to do the sensible thing and get me a proper 9v battery.

Feeling around the transformer after a couple of minutes connected and with the battery disconnected, I felt the OC81M's quite warm to the touch - the metal cap made me pull my finger away smartish. Would this be normal?
