Yes, just keep cleaning it. However these drums did wear and after a few years this jittering was normal. It may well improve with use, especially as it's probably been standing for years.

Thanks so much Anorak.
I try a deep cleaning, and i run the VTR.
The VTR is the first time, after 20 years starting to use.

Another thing most important for the Jittering back tension is the rewind idler,
after replaced, now the back tension arm jittering is really very low.
