<What do you think of them? Has anyone ever tried to repair the tape drive <capstans on them? Has anyone ever tried to built the probe for one? BTW <these date from around 1981 and are powered by Z-80s so they're on-topic. Simple fix. Scrape off the black goo or orange goo. then use a little superglue to anchor some plastic or rubber tubing over the metal hub to get the original diameter (some error is acceptable). I do this on TU58s all the time. Allison
