Single Chip Amplifier + Tone Control

This ambit is based on the National Semiconductor LM3876. This accessory is able of carrying as abundant as 56W of connected boilerplate ability into an eight ohm amount with 0.1% THD from 20Hz to 20Khz. Be abiding to accommodate an able calefaction bore for the package.

Use log pots for volume, bass and treble. A stereo amplifier can be congenital application ganged pots and a Stancor 402 agent instead of the 401.

Note that the commitment of ability to the speakers is primarily a action of the ability accumulation voltage and accommodation in Class A amplifier. In our case, we’re application a +/- 33 volt volt accumulation which is advised about a Stancor RT401 transformer. Use acute attention back alive with band voltages.
