Power Supply for Opus BT-C700

Hi all. I cannot seem to locate my power supply for my Opus BT-C700 charger (long story). Any suggestions for a replacement power supply? Thanks in advance!

Regards,
Frank A.

Looks like it take a 12 volt 1 amp wall wart PS—-nothing that special other than the connector size—from looking at the pictures looks to be the same as the Opus 3100—— here is a 2 amp that would be more than adequate
