Yep, finally finished it. The tonearm height adjustment collar was seized so I had to take the whole TT apart to fix it, that was a shitshow. Anyway, got it unseized, cleaned all the brass and stainless threads, lubed them up, reassembled everything after calibrating the tonearm. Sounds good, a very decent turntable the 1200mk2 is. I hear no rumble at all and it never deviates in speed
