Im having trouble getting any form of this type of oscillator working. Even a circuit I put together on 'Multisim'doesnt work and Im completly baffled as to why??
This circuit>> http://www.mediafire.com/view/?leybj0peqdrbq4b was built using the schematic on this link >> http://www.circuitstune.com/2012/01/astable-multivibrator-2-led-flashing.html .
As can be seen it is to the exact spec of the schematic but it doesnt oscillate. Instead the led's remain ON.
Ive gone over it a few times and ive been trying to get one of these things to work since Saturday night but no luck.
I feel I am doing something wrong because any circuit ive tried, even on Multisim hasnt worked even if they are exact but I was hoping that maybe someone can point me in a direction where I can put two and two together myself.
Thanks Guys
