Hi - does anyone have information on the mods to the FL2/3 published in the 80s which describe how to widen the notch filter? The aim was to make the filter more useful (less peaky) for short wave listening and involved replacing some caps.

I did the mods in the 80's but did not keep the information. It is a useful mod, and I now have a second FL3 which I would like to convert. I could compare the caps in the two units, but at first glance they look almost identical, so I need to narrow things down a bit.
Any ideas please.
