Have a +/-27V regulated switching power supply and TDA8920 power stage.. Work well as now, only 150W per chanel, but good for experiment! 3000W peak power...Hum?...

they didn't mention anything about which ic they use.
Fredos, could you post some photos of this amp ? just curious how they measure 3000W peak ????

Forget the 3000 watts peak...I just measure about 150W into 8 ohms and nearly the same into 4 ohms..It's a full bridge amp (each chanel) Powered with +/- 27V by an oversized switching power supply. Sound good, no apparent noise, I just buy it to look on how they can do an amplifier cheap like this...I will try to take some picture at the office this afternoon.
