Which pin of the LM3886 is for what? I suppose the unlabled pins are 3 of V+, V-, Ground & Mute? But in what order and which one not?
BTW Qucs is great!

Isn't an operational amplifier (OPAMP) doing the same thing? Qucs provides an ideal and some non-ideal OPAMPs.

If I do an AC simulation and my circuit contains two AC voltage sources. Which one is swept?
I am currently simulating an audio amplifier which uses a 230V (mains) supply voltage and an 1V audio source which should sweep its frequency from 20Hz to 20kHz.
Is it also possible to/should I do a parametric sweep? If yes: how do I specify that the frequency of my audio source should be changed, not...

Currently, I am simulating an audio amplifier connected to a loudspeaker with long wires.
Qucs already has some nice components to simulate two wires:
"4-Terminal Transmission Line" with parameters Z, L, Alpha & Temp
"RLCG Transmission Line" with parameters R, L, C, G, Length & Temp
"Twisted-Pair" with parameters d, D, L, T, er, mur, rho, tand & Temp
What I would like to see is a...

I think it would be useful to add a forum called "Feature requests"

Qucs uses "Program Files" where it should be using "Program Files (x86)" on a 64bit windows system, because it is 32bit software I guess.
Result: Can't find text editor.
Manual fix: change "Program Files" to "Program Files (x86)" in settings using GUI.
Using Qucs 0.0.15 on Windows Server 2008 R2 (64 bit)
Qucs is great! Tnx!

Very simple way is to do a screen grab.
Better - high resolution way - is to print (or export) the page as a PDF. You can then import this PDF into your page layout programme.

I can't seem to figure out how to export graphics, such as the schematic and graphs, etc, for inclusion in an external program (my word processor, for example). Any suggestions on how to get a .jpg or something out of Qucs?.

hi!
I don't know how to make a fourier series even if i've seen this solution
https://sourceforge.net/projects/qucs/forums/forum/311050/topic/2541818?message=5633897
this give me a strange result over here

maybe something is missed
please help me :(.

Also i add that is a little tricky to do power simulations! I tried to simulate a simple single phase rectifier and had some troubles with parameters of simulation.
