Not the same. Mazda was originally Edison's brand of light bulbs. I have several made in France 'Mazda' 12AX7S. These have bright nickel plates. Electrical characteristics seem to be normal 12AX7. Who knows the convoluted license agreements for Euro use of the 'Mazda' moniker? Obviously the JP automaker adopted it without Edison litigation. Perhaps all trademark/copyright are expired. The 12AX7S sound excellent.
