The youTube Video shows a buffer opamp in non-inverting mode used to amplify an audio signal by a gain of 10 dB (i.e. factor 3.2). I built up teh circuit on a breadboard and the circuit behaves correctly as explained. 

Now I wanted to simulate the circuit with EveryCircuit, but...:

This circuit modeled with EveryCircuit seems not to simulate the behavior of the output correctly: On the output of the opamp the signal has a DC offset of 4.5 V (this is correct), but the signal should  have a DC offset of zero V after the 10uF decoupling capacitor. but htis is not the case. 

Does someone knows the answer for this?  Greetings Richard

I like the "factor 10 rule" for filter, voltage divider, zener and all approximations guesses we have to do in life. ;-)
