Unknown tube in Philco 48-482

I've just started restoring this radio. I have a schematic, and while checking tubes discovered an unknown tube that might be hand-marked as a 7B6 where the schematic shows the 6SQ7GT should go. I have a 6SQ7GT but it won't fit in the socket. Did Philco change the schematic on earlier/later models? Can anyone explain this?

Thanks!
