Looks very good Sonnya.
I am also interested if the drivers make any difference.

It's OK to build and test, especially in P2P first, to evaluate sound acceptability with your speakers. The mosfet outputs version was checked many times, so you can swap from bipolar to mosfets if the speakers are too low Z - demanding.

The sun.....and garden work.... So i need to mesure BC560/550 and KSA/KSC. I want to etch a new pair of board since Irf pinpad are not sufficient nice for me. Eagle introduce larger hole when you switch form screen to printer. So i modify library in consequence. When all that's achieved i need the implementation/test step procedure....

Hi Busy Cat

I am a little lost...
please show schem of the the simplest version with mosfets OPT
thank you in advance

Hi padamiecki

The simplest of them all is in post #1.

From there on you can go more complex as much as you like, for example, constant current sources to supply input BJTs emitter current etc.

Sonnya, you tried to send me a PM but my box was full.
It should work now for a short while.
