Hi folks,
Have one where the drum is worn out. Nothing about, even Wiltsgrove doesn't mention, though must be popular with old folks who don't feel re-recordable DVDs are the biz, as they're truly crap.
Have chucked out quite a few earlier machines with other issues - DVD loader, DVB board, duff caps which popped drive chips.
Never held on to the drums so not sure if compatible, as the 49V isn't quite a Panasonic VCR, just cheap, used in all budget makes - Chris.
