The tank I have fits the serial number criteria. I haven't checked the plug to see if it'll shock me. I'll let someone else do that for me if there are any volunteers.

It wouldn't have any affect on the fish, as the stray voltage is isolated within the limp cords and plugs.

I have the coupon from here: http://www.current-usa.com/node/220 for replacement. I need to find the tank locally, and see if I can make the swap.

Ed, could you help me with getting one and making the swap?
