Oh, errrr OK.

Perhaps I should try harder but I don't think I could do much with an
LM3578 other than get the DIP version stuck on my shoe.

I'm quite serious; Read the data sheet, got no joy.

Well if he uses that TIP32C then he needs to back it off to 10KHz and
use something like a 47mH inductor.
