Wash the oxtails with warm water and place in a heavy stainless-steel pot. Add the onions, peppers, beef and chicken bases, garlic powder, salt, browning sauce, black pepper and cayenne pepper. Cover the oxtails by three-quarters with water. Bring to a boil and cook, uncovered, adding more water if necessary, until the oxtails are tender, about 2 1/2 hours. Adjust the seasoning to taste.
