I wish the wires in this app would auto snap like the do, but then have the option of editing where wire goes, sort of like LtSpice...

Start at output, 200uF at 8Ohm?

Lower cutoff frequency of ~100Hz.

AC coupled instead of DC.

LtSpice or other simulation with the trait outlined in the description... It would be convenient if users had a little more control over which direction the wires locked into place. The way it is can be convenient most of the time, but when it isn't, it can complicate the goal of producing a clean circuit.

I hear what you are saying. Once the wires snap into place you cannot adjust them. However, I must remark this app is pretty outstanding. It's accuracy amazes me.

@crake, why use a cap anyway? You choose symetrical power supply, if offset voltage is low, you wont need a DC decoupling cap!

@crake, nice circuit. This amp has a solid open loop gain of 1333 V/V.

@cspanbauer yeah, this app is outstanding. Thanks btw. Glad you like the circuit.

@hurz I chose the cap because I wanted the output AC coupled. No more complicated than that.

@crake, you do not get the point. Think about the need of the cap.

crake

@Hurz I understand. Other than a negligible DC offset at the output, and no need for the cap, what else could be done to improve this?

10Ohm as temperatur compensation seems to be overcompensated. Maybe 1Ohm, but this has to be calculated and dependes on your heatsink

it looks like a opamp. doesn't it?
