Charging the Albrecht

Several people seem to have found what I have written about the Albrecht AE2900AFS a.k.a. Dragon SS-301 and various other names useful. Now here's a chance for owners of those radios to help me.

The radio came without a charger. I haven't even seen one advertised for sale. No problem - I can make one. But I have no idea what the charging voltage should be. The manual is no help whatever. If you apply 12V or even 13.8V DC no current is taken - hardly surprising as that is not a high enough voltage to charge nine NiMH cells which probably have some reverse polarity protection in series with them.

Is the charger a regulated or unregulated wall-wart and what is the voltage and current rating?
