What is a normal quiescent current in BJT class AB amplifier
https://electronics.stackexchange.com/questions/220121/what-is-a-normal-quiescent-current-in-bjt-class-ab-amplifier
A BJT class AB audio amplifier has .27 ohm resistors between the push-pull outputs and speaker. There is 55mv and 59mv, respectively, across each resistor meaning a quiescent current of over 200ma. This is the lowest it can set to with the bias pot.
What is "Quiescent Current"?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero. Class A amplifiers vary the large quiescent current in order to generate a varying current in the load, hence they are always inefficient in power terms.

That looks like a good design, but I see two issues. One is that the typical idle current for an audio amplifier is 50 mA from emitter to emitter. Once they warm up you adjust the bias resistor again to get it back to a stable 50 mA. That is enough idle current to have low distortion, less than .01%.

Thermal transient variation of power amp quiescent current Linear Audio Vol 9 - April 2015. Bias current measurement test set The solution I chose is to wait for a zero crossing and then forcefully maintain the output current at zero until the end of the sampling interval. This can be done with a high-speed solid state power
