IMHO FR is a far better source for global news, than Radio Moscow.
The socket for the AC adapter usually incorporates a set of contacts to switch the radio from battery to AC. Sometimes they corrode. Try plugging the AC adapter plug in and out and wiggling it a little to see if it will start working off the batteries. Do it with the radio on, the ac adaapter NOT plugged in and the batteries in, so you can hear if it starts to work.

I don't use it for SW that much anymore as the web has become my primary source of information, but it wakes me up every morning at 5AM to my favorite classical station. When I am in the mood for some DXing however (especially on a warm summer night in my backyard), I can pick up just about anything that's available.
The web-site you linked says:
Requires four “AA” batteries (not included.)
There are no lithium “AA’s.” Does it have a lithium memory backup battery? Anyway, if you have a voltmeter, check the AA batteries. If they are rechargeable, your charger may not be working.
The earlier tips about corrosion in the AC adapter connector are right on.
I similarly bought such a radio about three years ago and it became unserviceable and unrepairable with a year.
Also, you might try pressing the reset button on the bottom of the unit. That may clear some electronic snafu within the unit.

Solder crack at the battery connection to circuit board
>> the AC adapter had to be purchased separately and is very large, heavy, and unwieldy <<
I think you’re operating here under some kinda misconception. I have the same radio. A very small power adapter is all you need. Take the Sangean to your nearest Radio Shack store. They’ll be able to fit you out with the correct 6V adapter and matching plug.
Just in case you are looking for a $100 Grundig radio..

Try CCRadio in N. California (Fortuna, I think), they handle Sangean and other similar products. At least can steer you in the right direction...
