What is generally indicated when a power transformer is very hot, and
the 7w power transistor in its vicinity is also very hot? The radio
works but will often "go quiet" after 10 minutes or so of operation.
Any suggestions would be greatly appreciated.


All the electrolytics are bad. Every single one of them. Eventually
they'll wreck the transformer by pulling too much current, or one of
them will explode and spew shrapnel all over the inside of the case.
Change them out.
