I've accumulated some Multiblitz Mini 200's over the years and have a half dozen units with 4 of them actually usable now. They're nice, small units with output that makes their ratings seem understated. I just spent quite a bit of time searching the net for listings of flash tubes in order to have backups ready as mine are aging and likely to need replacing, even with my very limited use. Is there a good listing of this information anywhere? I feel that I gave it a good try and didn't find any meaningful references on my own.
