![]() īeware it is an (unacknowledged, hidden in plain sight) flying rails amplifier. Redo using your actual measured voltages.īased just on PSU specs, but like Enzo once said, " the amplifier is just that thingie between power supply and speakers".ĮDIT: that´s some minimalistic power amp, just 1 Op Amp and 2 MosFets. * 4 ohm load: 40*0.5=20V RMS, meaning some 100W RMS * 8 ohm load: 40*0.6=24V RMS, meaning some 72 W RMS ![]() ![]() I have one of these with blown output, anyone have a schematic? Also, does anyone know what the power rating is? I found one place that says 40w, but can't find anything definitive, even the user manual says nothing about it.On unknown SS amps, you can estimate power :ġ) measure main voltage rails, as an example, say,+/-40V DC.Ģ) multiply that value by 0.6 if loaded with 8 ohms, by 0.5 if loaded 4 ohms, that will be very close to output RMS voltage, then do the Math, say:
