With later backelites it seems to be the case; indeed the tar does not soften as easy. Flooded eyelets do not help.
But there is only one, the line filter: indeed a convenient way to solder the line cord to. So my drilling and chipping hopefully is over with this radio, unless something else gives me the same problem.
The tubular caps seem to be a regular type with grey hard wax (I prefer softer brown one). Because of this yanking the terminal has to be done faster after heating as otherwise before you grab the cap with a piece of paper, after having laid down the heat gun, it is already solidifying. And even after pulling some of it remains inside, already hardened and stuck to the tube.
Not too bad; having enough practice with many hundreds of those I manage that well.
