This amplifier has 280W RMS at 8R and power supply (+ -75VDC), with a load of 4R the amplifier has a power of almost 500W RMS and heats up a lot.

Product described good, but I'm not really sure about specification. Need to verify. (measurement not done yet) What I would point out - the engineering work didn't take into account the different position of module except horizontal, therefore the resistor 390ohm/6W can really heat up the heat-sink beside in case of perpendicular assembly. IRS is also quite hot and I used only 71VDC for testing instead of 80... Let's see what will be the lifetime. I'll leave a note after measurement. Delivered fast - tall capacitors in the front of PCB bended slightly. (I'll replace rather)
