Stuck bandswitch on 620
#6

Be very carefull with it.

Unlike the switch in the Philco 60/66 which is a cylinder inside another cylinder, in these switches there is little mechanical possibility to really seize something. Possible but the ferrule is relatively short so with good effort it would probably rotate.

This is why before applying effort do make sure it is not one of the wafers that got really stuck, as if you try to overpower it it could break contacts.

Hopefully it is indeed the ferrule and some PB Blaster and heat (and then a lubricant) would do the trick.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
