Schematic errors are not unusual, although some manufacturers like Philco seem to have more then others, such as places where two lines connect where they do not, or not connect on the schematic when they should. An example is the Philco model 18 or 118, the driver tube is shown connected as a pentode, but in the real sets it is a triode connected pentode driving a pair of triode connected pentodes. I think that the people in the drafting department became confused at times, too many revisions, too many code numbers, etc. On parts lists of all makes it isn't unusual to put the decimal in the wrong place, listing something like a .005 as a .05 uf or something like that.
