Yeah thanks man, I have them boxed and ready to be taken to Fostex HQ Australia, which fortunately is located here in Sydney just down the road, so hopefully they have the parts on hand and won't take too long. I don't know how it works, if you have to buy a matching pair or if they match the driver up with the existing one, but in any case I'm going to ask to replace both drivers
Good to see that the wheels are in motion.
Also good that the trip to Tokyo may not be required. Keep us posted on the progress.
