Here is a Q&A exchange from one of the eBay Hong Kong distributors. I really don't knw if we ubderstand each other because I would think that little of an amperage difference would be negligible. But anyway, here goes... what say YOU?

From cassp-
Original PA301 states DC output as 4a, your unit lists DC output as 1-3.5a. Will this affect the operation of the keyboard?

From distributor-
Thank you for your inquiry.
Yes,this item output is 2-3.5A and it`s different with your device .it will affect the operation . Thank you very much.

STEVE - let me know how that works out. I'd rather buy from J&R than risk waiting for the wrong part from overseas.
