Good job! Maybe it is not supposed to sound like that, and you blew a transistor, but as I said earlier, that's how you learn, you will be able to at some point in the not so distant future, look at the difference in transistors (datasheets) and figure out why it doesn't work the same, at least it presented a "chirp" of some kind, and it worked, call it a variation
Bottom line, you experimented, it's what it's all about!
