OK everyone here is what I have found so far...these are subminiature Sylvania Developmental Tubes...The SD-834 directly crosses with a 6k4...the 804A is a triode, and the 806C is a pentode...Still looking for a pinout on the latter two, any help?

                                                                                                    Thanks,
