That's really strange.  The 50L6 had to be one of the most mass produced 
tubes of the octal tube era.  Maybe there's a page missing from the 
book.  Make sure that you are looking where the 2nd digit is a zero , 
not a letter "o".  It sould test the same as a 25L6 or a 35L6, just be 
sure to set the filament voltage to 50.  How old is the Hickok 6000A?
