Issue with simple blinking LED circuit using a PUT

Hello everyone,

I am having an issue with a circuit that is supposed to cause an LED to blink. The circuit uses a PUT in real life, but I reconstructed one out of two transistors instead. Is there a PUT component somewhere in CircuitLab?

Anyway, not sure why it isn't working. The issue could be that I don't know how to use the transient simulator as well!

Thanks for the assistance!
