Is the little bugger heat sensitive ( like an IC or a transistor?)

You don't mention the device to which you are actually referring.

Enough heat will damage anything ;-)

The frequency drift with temperature is small.
Sometimes people glue resistors and temperature sensors
to them to make "ovens", where they raise the temperature above
room temperature, and maintain a constant temperature to avoid
frequency drift. But we are only talking about a few hertz of
drift, and that is not important in the AM transmitter.

does the oscillator work like a transistor?they're both switches right?so if you made a circuit of a transistor with all other kinds of components,can you use that in the am transmitter project?

well I was afraid i might destroy it while soldering what Wattage is accpetable for this ( I am on 220 V Ac here.)

destroy what?the oscillator?with 220 v.?!i think its best to use 6 v. instead or 9 v. for better performance,..you might need a voltage regulator if you want to use 220 v. ...

Anything larger than a 30 watt soldering iron is overkill
for small wires. In general, use the lowest wattage that
will make the solder flow easily onto the wires.

To Mnado:
I was talking about soldering it.
