Newbee to head-fi, but have had cans glued to my head since first Sony walkman 4 of the early 80's! Bunch of Headgear and amps, but always went back to my YH-100's for some reason, (the sound man!!) and was surprised to see how much effort people are putting in to keeping them alive. Sadly, although the drivers are still prime, everything else is falling apart lol. I'm wondering if anyone out there has managed to accumulate any parts, or a burnt out pair, or could point me in the right direction to rebuild mine, other than Ebay, which has been picked clean.
