TESTING
I did
some testing and took some pictures of my oscilloscope.
I am *VERY* pleased with this circuit.... high headroom, nice sound.... large
output swing... 27 Volts peak to peak sine wave!!!! Man, this would bring
any DAT into submission! Resistance is futile. In decibels, that's +30dBu
Outputs!
And even at 100 Kilohertz, the sine wave still looks sweet. And oh yeah,
it can go down to as low as 10Hz.... no problem with headroom and frequency
response here.
27Volts peak-to-peak @ 1Khz
27Vpp @ 10Khz
22Vpp @ 100Khz
100 Kilohertz... all the bats and dogs in your neigborhood will hate you for it!
And some square waves
33Vpp at 1Khz
Great waveforms.
33Vpp @ 10Khz
The rise time is alright, but the falling edge is kinda slow.... Still alright I think.
22Vpp @ 100Khz
Okay, that last shot there at 100Khz doesn't look anywhere near a square wave. But only dogs and bats would complain.
