<div><font size="2" face="Arial">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.</font></div>
