The problems were first noticeable on AM. As it became worse it was more
noticeable on FM too.

The internal speaker is disconnected upon the insertion of the headphone plug.

Correct.

Have you ruled out corrosion on the headphone jack as a source of your
problems?

Yes.

Does the radio sound fine with headphones and bad with the speaker?

Yes.


Are the batteries fully charged,

Yes.

and if you have batteries in the radio as
well as using an AC adapter, is the adapter plugged in?

Yes.

If the adapter is plugged into the a correctly powered AC receptacle, and the
other end of the
adapter is plugged into the radio, when you turn on the display light, the
light should stay on continuously, and not go off again after (30?) so many
seconds.

True.

There have been individuals that thought that their radio was powered
by the AC adapter, only to realize that something was wrong and the radio was
running from the internal batteries. Unlike many other radios, when you insert
the AC adapter plug into the radio, the transition to the adapter from
batteries is accomplished by the presence of voltage at the adapter jack and
not by a simple mechanical switch operated by the insertion of the adapter
plug into the radio.

True.

Is your adapter correct for your radio?

Yes.

If unregulated, it should have nearly the same voltage and current specs.

It does.

I had a police scanner that wouldn't operate because I used an adapter from
another police
scanner that had the same voltage spec but had more current than specified.
(for you purists, apparently since it had greater ampacity, the voltage drop
was less when in use, therefore the voltage was too high for the scanner, and
it locked up).

Lastly, if you've eliminated all the above, and you find that your headphone
jack is operating normally, perhaps you can get an amplified external speaker
and plug it into the headphone jack. Be careful since I've seen more than a
few amplified speakers that produced a hum from poorly designed power
supplies, find a quiet one.

The problem is that the internal speaker died. I would like to replace it.
Thanks!
