This is from my heart, I never thought that my design of TDA7294 mono amplifier board will be so successful because there were many exiting boards, but what TUSKER has achieved in this short period is exceptional.
Tusker is simple, easy to make and delivers high power with many types of speakers.
Many people ask why the name “TUSKER”, after all it is a small pcb.
What can I say, small number of tuskers still roam the forests of our country,they are majestic.
So by using my pcb you may search the internet and know their plight.

The circuit is quite simple, main job of amplification is done by ic U1 and rest are the supporting components.
Input signal is fed to pin no.3 (Non Inverting Input) through R1 & C2. R7 defines the input impedance.
R2 & R4 connected to Pin no.2 (Inverting input) set the closed loop gain. Changing the value of any one these resistors will change the gain of the amplifier.
Pin no.9 (Stand by) - R6 keeps ic U1 in active mode by providing positve voltage.
Pin no. 7, 13 are positive supply, Pin no. 8, 15 are negative supply and 1, 4 are ground pins. Pin no.14 is the output pin.
Mute Function - Pin no.10 (Mute) is connected to JP2. To use the mute function replace JP2 with a switch.
Metal Tab of ic U1 is connected to negative supply internally, so proper insulation is necessary when fitting ic U1 on heatsink.
