OK, the T143 supply has arrived from Grace, and it isn't the one shown in the B & H photo mentioned above. It's fairly clear that there was some mixup between Grace and B & H, since the supply shown in B & H's ad is noticeably smaller than this one, and has an output voltage suitable only for a 12-Volt V3.
The output voltage of the T143 is 7.5 VDC (regulated) and the input voltage range is 100 - 250 VAC. The input power cable is a stock, standard IEC 3-prong detachable power cable; therefore no worries about "what if I lose this one," since I have a dozen of these and they are a stock Radio Shack item as well.
So this is not a wall wart; it's more like a typical power supply for a laptop computer.
The output cable is also very solid--no worries about strain relief at the connector (see photo; a white DVD-R is beneath the supply for size reference).
--best regards
