I have finished the radio and put it back together, and given it a polish.
I have not been over impressed with the radio, it has been difficult to peak up MW. The MW aerial coil was incorrectly wired, think it is OK now, but I cant get the MW oscillator to go up as far as 1548 kHz to pull in Gold. The concentric type of trimmer capacitors are pretty rubbish.
This chassis that KB used to make these adaptations must have been one of the early ones. There are alterations explained in the BR40 service manual (revised) on my website that explain a lot of the differences that I found.
Here are some photos.
