Hi
I know someone that re-tires phono idlers. Contact me
off list and I'll give you the info on him. He said
he'd give re-tiring a capstan a try if someone want
to experiment.

they're DC-100 tapes and you can use the same (40MB?) tapes that were used
in PCs. You can also reformat and use DECTapes. But check your drive first,
you'll probably find that it has the same problems (melted tape drive
roller) as the HPs usually do.
