There are quite a few Sony TV-900s here, Its a sort-of half way house between the TV9-90UB and the earlier TV9-306. Late 60s, 625 line single standard, UHF and VHF tuners, usually 5.5MHz sound -presumably imports from Germany. Inside it has a quite neat vertical chassis, early ones had the valved EHT doubler that 306 had, later ones are all solid state. I've seen them with German Siemens transistors in the IF strip from new, I wonder what that was all about.
