Not sure what exact refresh yours is from since they've been on and off the market over time but the original models started production in 1970. My Koss HV/1A dates to about 1974 and I replace the original ear pads from them every couple years for the cost of shipping so they definitely have loads of early parts.

Oh yeah, they're definitely one of the better early 70s dynamic driver phones that I've tried. I occasionally see them crop up for not a ton of money on ebay. Probably easier to find the RadioShack rebadged version (Realistic LV-10).
