I recently found a pair of SR-125s with pink drivers. I just couldn't help myself even if one side was out and the pictures were out of focus and of low quality. I could still see what seemed to be a pristine pair of 13-14 years old Grados, and boy if they were! 15 minutes after getting home from the post office, I had them open, but sadly I got no response when ohming the dead driver D: So, this is where I turn to you, the more experienced Grado lovers. From what I can see, both voice coils seem to show through the black wax-like putty covering the ends of the solder tabs. It's a bad solder job, but from looking at it I absolutely don't get the impression that the previous owner has opened and tried to fix these. The phones are so pristine that I think they must have broken pretty early on, and stayed in a drawer for most of it's life. These are definitely different from my old Grados anno 2006. The headband, while being made of some rubber-like material, are way softer than the new headbands. The lettering on the cups also seem more substantial, and have a less shiny chrome appearance. Maybe more in the likes of lightly polished tin.
PS. Can the voice coil itself have broken inside of the driver? Maybe the old drivers were of a lesser quality? Again I turn to the more seasoned head-fiers for their experience.
Also, maybe some out there are good at repairing voice coils? I'm guessing that Grado themselves don't supply or repair the pink drivers anymore.
