I happen to own a Panasonic RF 2600 radio which I bought new at a
Service Merchandise store about twenty something years ago.As far as the
performance of the radio is concerned,I rate it about average,certainly
nothing to crow about.On the bottom of the radio there is a jack that
says EP EXT/SP (for an extension speaker,I suppose) I have never used
any of the jacks on the radio before,but about two years after I bought
the radio,the radio would not turn on or light up at all.One day I was
poking around at the jacks on the radio with my fingers and I found that
the above mentioned jack was slightly loose.I poked a piece of plastic
between the metal part of the jack and the plastic casing of the radio
and it worked.But sometimes that tiny bit of plastic wedge will work
loose and the radio will not work again unless I mess around with that
bit of a plastic wedge I put there.As far as me takeing the chassis out
of the radio cabinet,and me not knowing how to repair radios,(unless it
is oviously a wire that needs soldering back together or a screw or nut)
I think my best bet is to leave the radio alone.I think the jack needs
to be tighned up,but there is no way to reach the nut from the front of
the radio.Some of my radios,if I pull the knobs off,there is enough
room,but just barely,I can tighten up those nuts.
