Hi all,
Well, actually it boils down to one question:
What shape a pinch roller should have? I mean the part that meets the capstan shaft. Is it supposed to be perfectly flat, or rather slightly convex?
I`m trying to make a Sony TC-K515S great again, but I encountered some resistance in form of deformed pinch roller. I sanded off the deformed surface and now the roller is as flat as I could make it. It doesn`t visibly mangle tape anymore, but there are still sound artifacts, most probably because of uneven pressure on the capstan shaft. I suspect that I could make it too flat.
I examined rollers in my other decks and all are slightly convex, however since the other decks are quite old, I can`t tell if it`s not natural wear.
