The professional PCB's has arrived, and I have finally made it.

This is my prototipe done for selling, please don't ask for schematics sharing, because I will not make public, thanks for understanding.

Power supply +/- 95 Vcc, input level 1,00V RMS, for max output below clipping.

Some pictures:

And last tests:

Made today, In all 3 types of signal, Sinusoidal, Trianglewave and Squarewave, at 3 Khz,7 Khz, 10 Khz si 20 Khz, on 8 ohm dummy load, at 1-2 volts lower on output below clipped output:

Why ask any technical questions without an schematic to follow?
Doesn't make any sense.
Just be a waste of time.

sdman , as I told, being my prototype, it was made for selling, I cannot share schematics, thanks for understanding.

But I can share oppinions, or ideeas, too, just ask!

Those modules will cost between 150 and 200 euros each piece, dependind of what output devices I will use, 2SA and 2SC Toshiba's or MJL On Semiconductor, which are more expensive...

I didn't ask for an schematic, I was making a point that you can't ask any intelligent questions without
a schematic/topology to look at.
The members of this Forum who buy your boards/modules deserve to know what they are getting.
Also this is an DIY forum where people learn and exchange their knowledge and ideas, not to just push and sell a product.
Other Diy forums have a policy against this or they have a Vendor section that you can advertise from.
I could care less about your schematic, and I think that you are not being fair to the members of this forum.

When someone will be interesed about mine modules to buy it, once with modules , it will receive full technical support and schematics too.

While you send schematics to any one who will buy, then he can post it after that for free.
and you end up with your schematics published! :rolleyes:

So I think you can show it, without part numbers

If the one who will buy it want to do that, is his opinion...

Anyway, the schematic will be without values!

I think you're in the wrong place to upload something without framework?
my schedule does not interest me because I think any technique that you will buy only those people who do not have the knowledge to build a class AB amplifier


creo que estas en el lugar equivocado, para que subes algo sin esquema?
a mi tampoco me interesa tu esquema porque creo que ninguno tecnico te va comprar eso solo aquellas personas que no tienen el conocimiento para armar un amplificador clase ab
