Had to take the space command chassis out as the volume stepper wasnt cutting the volume down, rather intermittent. When I went to clean the wiper switch, I noticed this folded tag inside the case. It turns out to be a factory quality control repair tag. Apparently the 37.75 hz section must have had some kind of defect and was serviced. Who ever put it together must have still been hung over after new years 1973. You can see all the different check offs that could have happend durring assembly. This tag was for radio assembly only. Would like to see one for TV, but that will probably never happen as there is no place to "hide" the tag on a TV chassis.
As for the space command chassis, its actually a better design than the previous ones. This one actually has plug in transistors. Earlier versions of the 600 vertical chassis had the transistors soldered in place.
