Don't get too fussy with the shade of gray. I have several original Altec cabinets here (A-4, A-5 and A-8) of different generations and no two are exactly the same shade. I've had some custom paint made up at Home Depot, but actually Behr "Evening Hush" 770F-6 is a surprisingly good match and available "off the rack".

If the orange paint is well applied I'd forget trying to remove it. I'd give it a light sanding, and then get a good primer like "Fresh Start" tinted to match. With a coat of primer and a good top coat or two you should never see the orange again.
