Apelco 510 Handheld VHS Power Supply
 

Does anyone know what type of power adapter this unit uses to charge the
batteries. The primary coil on my original is open so I cannot determine if
it is a linear regulated or simply an adapter without regulation. The label
on the old adapter rates the output at 12 VDC 200 mA. This is used to
charge a 7.2 volt battery pack. Any help would be greatly appreciated. I
would prefer to buy an aftermarket rather than pay the premium price from
Apelco for what appears to be inexpensive unregulated adapter.
Thanks in advance,
Randy
