I'm about to fix a 8296D. The internal 8250LP has a pair of JU570-2 
drives with pretty obvious traces of capacitor leak... they definitely 
need a good cleaning and recapping. In this thread (already mentioned on 
this list about half a year ago, 
http://forum.classic-computing.de/index.php?page=Thread&threadID=7382 ) 
there is a precise list of the used caps.

I've already recapped some of my vintage machines in the past and used 
ceramic and tantalum caps as replacements whenever possible, so that 
they won't need to be fixed again (and the implied salvaging could be 
avoided...) at some unpredictable time in the future.

The JU570-2 seems to be a simple case, except for the three bipolar 
electrolytic capacitors (10uF 25V), which just can't be replaced by 
simple tantalums.

I'm asking your opinions. What, if I simply replace these caps by todays 
cheap 10uF ceramics?
