Battery gunge can often cause short circuits, so a magnifying glass and a very strong light is a good idea. Your worst enemy though is going to be corrosion, as you might have already guessed. This might also mean removing the circuit board from the other part of the case to look on the other side of the board. I don't know that model, but you could look online for a service manual, trying some of its other identities. Perhaps Paul or Gary might be able to help as they are familiar with this radio.
The spring terminals are often stainless steel or plated. They'll usually just wipe clean. The others may be copper or brass. They might need a bit of help with an abrasive material. An emery board donated by my wife has stood me in good stead. They have separate grades on each side which is handy and fits into places my 10" rasp won't.

Thanks, Tom, I have done most of that, but will try it again - with a magnifying glass :-)
I fear the original battery leak may have fed alien voltages to parts of the signal processing circuitry. But maybe it can still be saved. Any additional ideas will be most welcome.

I have an AR-1733. It was good. Sadly the batteries leaked and it is now dead.
