This was my first BBC2 receiver:

I "converted" it, the picture width was lacking so I reduced the picture height to get the right ratio, can't remember the exact details of the mods I did but I retained most of the original IF circuitry and it tweeked up, not perfect but was ok from a distance, it was my bedroom telly.
