Since this circuit operates at 1.5 Volts, Any capacitor with a rating Greater than 1.5 volts should be OK.
Therefore if C2 = .01uF at 50 volts, which should be quite common, is Perfectly ok.

C3 is Any Air Trimmer capacitor that is aproximately within that range. Its not al that critical.

10K is 10,000 Ohms.

L1, What is your problem?
Just wind a coil as it explains.

No it doesn't. The obsolete LM3909 voltage-doubler IC boosts the 1.5V battery to nearly 3V so the LED is bright and the FM transmitter pulses.

OOPS, I Never looked at What IC was being used.

But I doubt he could find a 1 1/2 volt cap anyway.

MERRY CHRISTMAS.
