STEREO LM4766 AMPLIFIER
Stereo amp using the Gainclone LM4766 chip which has a great power output about 2x40 watts.
The PCB that I designed already has a preamp and also has a speaker protector upc1237 which makes it have complete functions.
There are also 7812/7912 voltage regulators which makes the voltage to the preamp stable.
This circuit requires a voltage of 18V-0-18V from the transformer, if needed you can increase the maximum voltage to 21V-0-21V but by changing the relay with a higher voltage capability
** don't forget to add the 560pF capacitor (C21,C22) in the bottom layer between the middle leg of the volume potentiometer and ground
