[Milsurplus] Crosley REP with Bad Audio Output Tranny

[Bruce Gentry]

If you can get the end off or otherwise open the case a bit, immerse it 
in gasoline for a week or so. Use a covered and loosely sealed container 
so fume pressure can escape when it needs to, but otherwise trap the 
fumes. Set it in a warm place outside, agitate it avery day. The pitch 
will dissolve.  For a faster but risker way, get a cheap hot plate you 
don't mind losing, and use a double boiler to steep the transformer in 
very hot kerosene.  Use a variac to keep the water in the bottom pan 
just simmering, and of course, do it outdoors where  an accidental fire 
won't harm anything. The transformer core and windings will usually pour 
out of the case easily after a couple hours. I haven't had it catch fire 
yet, but it can and you must be prepared if it does.   Now for a bit of 
history:   Between the World Wars, critical massive machine tools were 
preserved by mounting them on worn out railroad flat cars, then spraying 
and dousing them with molten tar. They could then be stored outdoors 
with little chance of rusting. When WW2 broke out, the cars were pushed 
through tunnels where they were showered in steam heated kerosene to 
wash the tar off.  The preservation was excellent, and the tar saturated 
kerosene was then used to fire the boilers.
