audioguru said:No it is not! Look again. The PNP transistor is backwards.
If its supply voltage is about 9V or higher then the transistor would conduct all the time like a 7V zener diode.
A backwards transistor has a current gain of about 5 instead of a current gain of 200. So it might light the LED dimly.
that would be my bad, i said in a earlier post that i had the transistor from C B E and it was working, but in fact!!! i had it at E B C the whole time, I just read and wrote it down wrong, i knew how the transistor worked from memory, bet couldn't remember the names of the pins.
