I have been thinking about the issue of adjusting the IF transformers, I couldn't remember what they looked like so went and had a look at my FB10.
Here are some photos.

My radio appears to be a MK1 model with the frame aerial and 6BW4 output valve and 6X5GT rectifier.
As far as I can see all models appear to have the same part number for their IF transformer.

In my radio it is easy, with a fine screwdriver, to turn the thin brass screws to adjust the IF, there is an adjuster above and one below each of the cans..
