Had some PMs, questions on this. Answering here.
I use a Western Digital external hard drive AC adapter. See attached image.
The 2.1mm tip fits, and the power specs match.
It's 12V 2A (12 volt, 2 amp), center-positive
The OEM provided supply was 12V, but amps varied (as it always does with DataVideo and Cypress TBCs). It call for 500mA (0.5 amps), but amps don't really matter that much. You can use up to 2 with no problem.
Anybody in Australia, UK, or other European countries are encouraged to post about what you're using, or what you've found.
This advice also applies to the DataVideo TBC-1000, which can also use 12V 2A center-positive AC adapters. The unit is rated for 12V 1.25A minimum, and 2A max is fine. Furthermore, the DataVideo 2.1/2.5mm tip entry is more universal, and allows power supplies from
Fantom, Seagate, and many other external hard drives.
