A newer version of the schematic then, incorporating some of the feedback. The simulator reports 13.5 mA at the LED and 430 ?A at the base for an hFE of 32. I didn't change the 10kOhm resistor of the base to 4.7kOhm as that would give an hFE of 16. It is still not entirely clear what the hFE should be and since it is a loose value anyway and the datasheet does not give the value of hFE for 5V i guess an approximate value of 30-70 should suffice.
