Ah, good ol' 5965s. These were a higher-spec version of ... some really common tube which I no longer remember. The Bendix G-15 was wholly based on them. I probably have one or two around the house since I kept one-of-each of the plug-in cards when my high school scrapped it. (It would have been too heavy even for *me* to haul around all these years.) I still have the technical manual, complete with the FE's hand-written annotations. mcl
