Thanks to both of you...Meindert-I don't understand the notation "2k2" or
"4k7" in your post. Would you please explain?

One caveat: if the .33 resistor or fusistor blows, you get 12V through 100
Ohm at the base of the transistor. This will produce a current of 120mA at
the base, which will kill the transistor. A base resistor of 2k2 to 4k7
will
do the trick.
