Biasing a Tube Amplifier | Amplified Parts
https://www.amplifiedparts.com/tech-articles/biasing-a-tube-amplifier
These amps require a bias adjustment for the tubes to operate properly. With a properly biased amp, the amplifier will work more efficiently and will accurately amplify the sound of the guitar, pedals, and preamp. An incorrect bias setting can result in crossover distortion, inefficiency, and can cause damage to the tubes and amplifier.

Amplifier Biasing - CH Precision. Amplifier biasing. Home / Technologies / Amplifier Biasing. The bias current applied to an amplifier’s output stage is a critical factor when it comes to both technical and musical amplifier performance, establishing the optimum operating conditions for the devices chosen. In fact, the bias current is so critical that many high-end amplifiers use …
What the Heck is Bias? | Adjusting Bias in Audio Equipment ...
https://korneffaudio.com/what-the-heck-is-bias/
So, for most amplifiers, there needs to be a BIAS signal added to it, and this makes the amplifier play nice with the audio signal. The type of bias signal can be very different depending on the component, and the circuitry involved can be different, but in general, all bias signals push an amplifier or a component towards efficient, linear ...

Measure the voltage across the R5 and use Ohm's law to calculate \$I_{E2}\$. If it is "in the ballpark", the bias circuit is working as designed. without them, Q2 goes into saturation, and is basically bypassed - the amplification is done by Q3 alone. Q2 isn't configured as an amplifier in this circuit, it is an active load (current source) for Q3.

You have AC coupled the input, which makes sense for a audio circuit, but added no deliberate DC bias of its own. Only the middle stage has a deliberate DC bias, but this is AC coupled to the output stage so that bias does not follow to the output. This circuit also can't seem to make up its mind whether it is meant to be single supply or not.
What Is Tube Amp Biasing? How It Works, Why You …
https://www.sweetwater.com/insync/what-is-tube-amp-bias/
If I’ve interpreted the above two explanations correctly, then, in the case of an amp, bias is a voltage applied to a tube that controls it and makes sure it is working properly, too. That’s still way too vague for me, I’m afraid. “Works properly” and “control” are more than a tad cloudy. I need to know more — a lot more!
low-biasing or high biasing in Class-AB amps | diyAudio

every time you build amps especially Class-AB , biasing plays an important role in the sound quality of amplifiers in terms crossover distortion elimination... many times we came accross good designs which are both low-biased ones and some are high-biased ones..what i refer to low Biasing is the idle current of output devices between 10mA to 65mA and above …
