I built a steam sound for my #9 tank many years ago from a simple Picaxe white noise generator. It was a very harsh sound. When I built my #20 tank, I managed to design a Picaxe interface which allowed the chuff to be shaped and volume controlled. This sounded really good, so I changed the old #9 circuit to the new one. This video compares the sounds.
