I did one of these a few months ago. I found the way the tuning capacitor was attached to be somewhat unusual. It has long springy wires coming from the chassis to screws on the capacitor frame. They were all disconnected on mine leaving the cap free to move but when I re-fastened them all the arrangement actually works a lot better than it seems it will.

I never managed to get much out of the foil aerial, though.
