I am trying to get a Vax-11/750 machine up and
running. It looks like the TU58 drive
is suffering from the 'gooey roller syndrome'.
I see that people have successfully used 1/2
inch (ID) Tygon tubing to replace the
goo. Is there any specific type of Tygon tubing (eg. R3603, R2000, etc.) that is used?
I don't know the particular variety I used in mine - I just went to
the Lowe's down the street and bought a foot of 1/2" ID tubing -
whatever they had on the shelf. I was unaware of a large amount of
varieties of tubing, so I just used what they had in stock, and it
I started that many years ago like 1995ish. I spec'd Tygon (brnad name)
as that was available to me. Most any generic Vinyl tubing works so long
as it fits tight and has enough wall thickness.
After about 10 years it tends to get hard, the fix is obvious.
