Good day Thimios...

Amp is working now as advertise.... Thanks a lot for your help... cannot give feedback as to the sound quality as I do not have a test speaker at work... only dummy load.... I'll connect a speaker and some music source tonight and give feedback....

It should work very well, I did it the PCP design 🙂 and I have two pairs working very well.

Good Day Kandimba....

Thanks for the PCB layout. I can testify that circuit is working well with +-49V supply. Very powerful and clear sound.

I'm in the process of building your AX20P PCB layout and will post feedback soon.

Thanks to Sir Apex for the circuit and to you SIR for the layout...

AX20P Singing....

Good Day....

Thanks to Sir Apex for the AX20 circuit and a Big thanks to Kandimba for the PCB Layout....

Completed AX20P....see pics attached....

Thanks Sir Apex and Kandimba.....

One question....how much bias current for this circuit???? How do I adjust the bias current??? Here is what I am doing....

I measure with DVM across 0.33R resistor. I use ohms law...V=IR...6.6mV=20mA x 0.33....Is this correct????

Regards,
macd.....😀😀😀

Good Day Sir Apex....

Thank's for all your audio designs...I am very grateful...

I've just completed an AX14P and an AX20P amp design, both using Kandimba's PCB layouts... Both amp's have great sounds...

Just one Question... I have a mixer with balance outputs. How do I connect mixer's balance output to input of amplifiers?

Thanks in advance...

macd.....🙂🙂🙂

Good Day Sir...

This is what I was looking for...Thanks again...

Just some feedback...I connected my AX20 yesterday with proper speaker and supply. Sound is very nice, but I like AX14 sound more. Better trebles and bass. Tested both AMP's with same setup...same psu, input mixer, speakers.... AX14 my favourite..

Thanks again for all your designs...

Regards,
macd🙂🙂🙂
