Im new, first post, so if this is not the correct location, please let me know where to go.
Ive just downloaded LTSpice and am new to that program. Trying to setup my first simulation of a transistor multivibrator, but it's not working. Just showing constant output. Can anyone offer any advice?

Since the circuit is perfectly symmetrical, with components identical on either side, there is no way for any instability to arise. Make one of the collector resistors different.

Also, check the simulation box to start the voltages from zero.
