I have multiple Sonys in my collection. I have one that resembles the First Trinitron very closely. Sony model # kv-1212 , made around 1972 or 1973 according to Sams Photofact. Both tuner knobs and crt mask done the same way, where mask has cool flat look on crt. will post pic later. I think this is the cooolest and most modern trinitron when set is off, looks similiar to a flat screen TV. The picture is awesome too! Where color badge is on fist sony, a AFT color light bar is there. Does anyone know of other 70s Sonys that use this unusual crt mask with flat knob UHF tuner knob?? Smaller front knobs have different arrangement.
