3 amps?  Should be no problem.  The original supply was rated at
either 1.5a or 1.7a at 5vdc, and the 64 very nearly drew that much.  

I used a 2.5a Apple supply for quite some time with great success
(with a 1750 and quite a BIT of other junk).  Now I use a very nice
big heavy 5vdc supply that could power most of lower Florida (and
certainly the 3 or 4 64's I have on it)  :-)
