Nice work, but wrong 2N5401 pins layout, use layout from post #126.
Hi sir apex
i dont have bat85 diod
1. can i use 2 paralel 15v ziner instead bat85 ?
i can not find 1% resistor in my town.
2. can i use 5% for that ?
3. i ask again you dont have 2n5551 in your D200 amp board even in O/C section ?
new pic

in post #126 all TO-92 case is in other side.
change all 2n5401 and 78l05 too ?
Yes just rotate all TO-92 cases, and use 0.05R instead 0.15R. O/C current is 0.55V/0.05R.
Use 74AC00 instead SN7400.

i try to upload video but can not
my video file size was 250MB for under 2 minets
sorry
Post video file to me apex@eunet.rs thanks
sir my internet speed was 3kb/s
my isp was error about 1 month.
i was working hard with computer
some thing has error in my board
when i increase volume the sub woofer dont work and just creat sound like gher gher gher.
i try to upload 7 second video file.
i was control the input current it was very low when the volume is in top.!!!
the current was 0.03 A
why ?
we need a good preamp for use full power.
and good smps too.
i dont have any smps. i need a powerfull smps.
