Suggestions for repairing HP tape drive capstans?

Indeed.


> A = USA
> G = Germany
> F = France
> S = Signapore
> B = Brazil

Some others that I have seen

E = England
J = Japan
K = Korea

(The last 2 I've seen on monitors made by NEC and Samsung respectively, 
but badged HP. They have an HP style serial number.)

I've alsoe heard that 'Q' was used for England at one point, but I have 
never come across this.

Getting back to tape drives, the units I'ev looked at are, indeed made in 
England (with an 'E' in the serial number). I've also just stuck a ruler 
on the metal hub of the capstan from the 9144, it measures 15mm, and is 
considerably more that 1/2". Of coruse a ruler is not as accurate as a 
micrometer, but it suggests that my measurements from the latter tool 
could be correct.
