with volume control and switching headphone jack.
Input voltage: 2.5 to 5.5
Jump R3 & R6 to use the full power of the amp, otherwise use the 2 voltage dividers R3-R4 & R5-R6 to lower the inputs. Useful for lower wattage speakers or to prevent distortion.
The 10k resistors under the volume wheel need to be 20% the resistance of the volume wheel. If you aren’t using a 50k pot, adjust accordingly. These serve to convert a linear taper pot to a logarithmic pot.
All components 0805
