Of course one should examine the actual circtuit to be sure, but if they're the usual (for the '80s electronics) supply bypass or DC block ones, the MLCC will work even better of the original. I wouldn't dare using an MLCC in place of electrolytic as a switcher output capacitor unless I really checked what I'm doing anyway. > Rob > > On 21 August 2017 10:23:03 CEST, Julian Perry <email@example.com> > wrote: >> >> Just a sanity check. >> I've an 8250LP drive that I know was working well when I stored it. 4 >> years ago. >> cracked it out today to check it out, as one does. :) >> It happily reads and writes on a preformatted 8250 disk but will not >> format on either drive (error23 track 1/17) >> Can I assume it's a spindle speed error?
