Dear apex sir ,could you provide me SR30 PCB design pdf file so that i can build and test it

Very nice work Home made does not mean poor quality. I love the temperature measuring device.
Regards.
I do not want to hyack afcouse but only want to let see mine design class d amp, I did get extreme low distortion, using PI-integrater combination for linearization, and safe shift for doubling carrier, but do not now how it sounds yet. busy with a hybrid and circlotron, but now with our extreme summer here, I enjoy first.
Nice amp by the way, vertical mosfets? drive them with beefy drivers, get more sweet spot then.

Nice!
Can you help us finding the pcb version that used here?

I'm still learning LTSpice:
Is there a difference between running an FFT on the current (you have I/R16 selected in the screenshot) rather than on V/VOut at the load?
Do you have a schematic to share? It sounds quite interesting.
Cheers
I don't Remember witch page i copy this schematic sir

Hello desertstorm,
Nicely built. BD139 is better mounted on the main sink.

Or if you follow Doug Self's book recommendation, place BD139 over one of the output devices. In this case it would have to use short wires to do so.
for me its okay this amp tested whole night using karaoke player but nothings happens still singing loud and clear..thanks for your comments regards..
If you set bias current too low it is OK, and the amplifier work near class B. The crossover distortion become high. If you set the volume down and it SPL is so small but you can hear clearly, you will notice the distortion, especially in high frequency. But training people can easily hear the crossover distortion in any volume.
