@FreezEntertainment Im audio service technician. The circuit was connected to the line out of a mixer, so the signal is some mv. no problems for the red led! Thanks for the comment anyway

@FreezEntertainment only for test reasons :D

Yes i agree, But this is a line vu meter, so the amplifier was not peaking. I put also a sensivity pontetiometer for this. Thanks for comment. (I upgrade the circuit, soon i will upload a new video).

Great job! But how come you had to use a power-transistor? Was that a 2n3055 ? You just didn't want to take chances,right? :P Loved it! 5/5!
