DC Power Plug for ZOOM 9002 AD-0001 power adapter. This is a 1.3mm I.D. by 3.5mm O.D high quality barrel type solder plug for direct replacement of the AD-0001 power supply's tip. These tips are also know as: SIZE: H
It is fairly common for the tip of the AD-0001 power supply to fail causing intermittent power problems on the ZOOM 9002. If you can gently bend the cable of the power adapter just behind the tip where it connects to the ZOOM 9002 and the power goes intermittent it is most likely a bad DC plug (tip). The original ZOOM AD-0001 is a very good power adapter with excellent filtering, you are better off fixing the tip of an original AD-0001 vs. using an aftermarket replacement adapter.
Ensure you install this new tip with the correct polarity, the ZOOM 9002 is clearly marked on the case and uses a center negative, outer positive polarity. Connecting the polarity backward can instantly and permanently damage your 9002.
