[Hallicrafters] removing nuts holding selectivity switch to chassis

[John King]

I am attempting to loosen the nut holding the selectivity switch to the front of the chassis. Do anyone of you Hallicrafters mechanics know of a good way to loosen the recessed (to the panel) know a good way to loosen the nut holding the switch to the front of the chassis. I have a guitar wrench that is good to remove nuts from a panel without scratching but this nut is recessed and holds the switch to the front of the chassis. Anyone with experience removing this particular switch for capacitor change? Please advise. Thanks, and 73, John, K5PGW,
