I never took apart my Grados (can't take apart the RS1s at all it seems!? (not that i'd want to)) but on the SR125s (so presumably the same on the SR60s) there is some little clips next to the white fabric... if you unclip those, does it reveal the drivers?

I'd suggest waiting for a response from someone who has tried... before trying it yourself though... but if you can get in... there may well be a couple of hairs that've made it all the way inside the assembly?!
