I've seen this circuit, and I tried myself replacing the transformer with 2 470ohm resistors, but it failed to work. I asked my college lecturer why, and he said that the transformer acts a an inductor. You can buy inductors, but they are probably just as big and expensive as the transformer. You can't easily replace it in a word.

You might want to try a 555 flasher if you really can't live with this transformer, or if you need the circuit to be compact.

Yes I do.

Just take your soldering iron, and burn the transformer and then brush the pieces into the garbage LOL

ok, I was only joking. Here's the real answer:

Do a search on a "relaxation oscillator" or a transistor flip-flop.
