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 E 2. 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.
