... is too complexity ... oh,my head ...

Yes, I know how feel.



Like some little circuits made by

Hello,Lineup:

think you for your words.I even forget this thread before you up it!
I didn't giveup with AF AMP DIY...and I still carry on...
this 10W FET amp really sounds good(sweetly & Warmly) when I using K1056 as ouput devices,here is upgrated version below:

thanks DarkHorse

thanks, DarkHorse

I like Lateral MOSFET very much!

For nice Power-Amplifier:
2SK1056 ... 2SK1057 ... 2SK1058 ... 2SK1530
... 2SJ160 ... 2SJ161 ... 2SJ162 ... 2SJ201
For good Pre-Amplifier:
2SK216 ... 2SJ79
and ... 2SK213 ... 2SK214 ... 2SK215 ...

I will have a look at schematic.
Maybe I see some thing I can use or make, myself.
And maybe I learn New Good Idea!

I think the amp would benefit from a servo loop.

hello Wavebourn:

Please show me your idea with a picture!
this problem is still my puzzle,input stage isn't got full DC feedback from output point,this can make the circuit works not steady...
any commend, please reply,thanks!
