I didn't make it It's in a book that I read when I was a kid it didn't work then and it still don't. I was reading about tone generators and it had all most the same circuit. But it had a waring to check the 2N3906 to make sure it didn't get hot it said if it did to change the
resistor and capacitor
This is a power dissipation of 77 milliwatts
I made this tone generator went threw the wiring it's hooked up just like it shows but it burns up the 2n3906 when I power it up. Is the book just wrong.
Perhaps but Google does not find 8000r, 8000 ohm, or 8k ohm earphone. Not a standard item. However, you did include a smiley.
