First Post!!
I called Sony about the D5 repair and they said it's out of production (yah) so parts aren't available but they'd check it out and so long as all it needs is some kind o maintenance/cleaning they can work on it.
I'm sending it off to see what they can do. My problem is the take-up reel; it's stuttering and hesitating and not keeping up with the capstan, leading to tape eating.
I'm hoping it's just a lube issue but my gut is telling me it's a belt, but who knows.
