Hi Cosmos
I recently picked up my third pair of the Nines and from what i can see my serials are the same as the user "thphoto" so i guess he sold them to the guy in NH i got them from. Do you have the .pdf of the rebuild procedure that is going around at all? My sel. diodes need to be changed. I love this speaker even though I have A-3s and the zA2.1 as well. Thanks Rdiiorio
