I found the item number and DigiKey part number for the wall wart I purchased: WSU045-1500-R # 237-1414-ND This is a 4.5 VDC 1.5 A unit. They sell higher power units at 2 A and 3 A for a slightly higher price. I am going to surmise that the list would claim had I purchased the 3 A unit I would still be having similar problems with this tapestry... :-) Regards, web... --=20 William Bulley Email: web@umich.edu 72 characters width template ----------------------------------------->| --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
