audioguru said:The collector voltage of the PNP is always much higher than the voltage at the base of the NPN. Therefore there won't be any positive feedback, the LED will just be turned on all the time.
It might work if you carefully make a voltage divider to reduce the 2V to 2.3V at the collector of the PNP down to about 0.55V to 0.65v at the base of the NPN.
