The deal on the 50B5 is that plate and heater pins are next to each other which there could be a possibility of arcing. It was superseded by the 50C5. 50C5 same tube specs but different pinout to limit the arcing possibility. 50A5 and 50L6 along with the a fore mention tubes have same specs but bases and or pinout are different so none of them are directly interchangeable.
