I purchased this power supply from Sam Ash after buying the Tascam DP008-EX separately in a bundle package - not from Sam Ash. The power supply that came in the bundle did not even fit the Tascam unit, and it obviously was not rated for the proper power required by the Tascam. I recommend that all buyers spend the extra dollars and purchase this adapter model. It is worth the extra dollars to use a power supply rated for the Tascam. You don't want to risk your equipment with the wrong supply.
