Class D amp module build, silly power...

[Reid Malenfant]

Right, i have established that both modules are 100% working I'd have prefered to test them on a current limiting PSU but i don't have one handy, that will have to be remedied

I simply put a resistor (47ohm) in each power line except for the ground connection & connected it up to the PSU of the Fisher amplifier i mentioned earlier. No smoke, LEDs on each module lit up. Low 1mV DC offset with approximately 0.1mV of AC noise on each output. To test if they amplified i fed them a bit of good old AC hum by injecting it via a screwdriver & finger

Not very scientific but it did the job Now to get a decent PSU rigged up & some real testing

E2A:- I have purchased a 500VA 0-35V 0-35V toroidal transformer which should do adequately for the PSU. The result should be at least 120W RMS with an 8 ohm load & hopefully 200W RMS into 4 ohm per channel. I have a nice pair of 33,000uf 100V computer grade electrolytics & i know i'll have a 35A bridge here somewhere, so effectively the PSU just needs putting together now
