[Heath] SB receivers and in general ferrite coils

[Patrick Tocornal]

Does anyone here knows how to loosen up the ferrite core in the antenna/plate/oscillator coils of these receivers, fortunately I have only one that is stuck, have the right tool but it wont budge, is the 3.5 antenna coil and by the performance of this receiver it need adjusting like all the others. So far I have used heat (wife hair drier) and cold with a medical freezing spray can to no avail, is there some kind of penetrating lubricant that could be used without making it worst ????? Any help would appreciated.
