i dont have 74hc00 , irf640 , tl081 , cap 224-250v , res 510 ohm 1% now.
i buy that tomro.
An externally hosted image should be here but it was not working when we last tested it.

very thanks sir apex
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
thanks friends

Use 1N4148 instead BAT85, use 5% resistor and all transistors are 2N5401 but pins reverted also 78L05 pins reverted. 220nF caps can be 100V dc.

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.

Hi
i rotate all TO-92 cases
i dont have 0.05R. 0.15R is best i have.
i have 74HC00 too. dont have 74AC00.
ok ?

ok ?
i was use 47uF 35 volts for cap and 10uF 25 volts for one
every things is ok for test
i test it with + - 25 volt DC

74HC00 is ok and you can use three 0.15R in parallel to get 0.05R, but 0.15R is ok for test (O/C current is 3.6A thru speaker)
Hi sir apex
very thanks for your good amp
sound is very good even in HI FREQ like sir manoj amp just his amp has beter power than your amp.
nothing is warm even mosfets and filter. i use T106-2 core.
how can i use this amp in 2 ohm ?
some pic for sir apex D200 amp
very thans good enginier

D200 can be use with 2 ohms load without any changes, just 0.05R in O/C detect circuit, and this is full range hi-fi amp work on 450kHz, for more power increase input level with preamp.
Nice work, can you upload video on yutube?

i dont use preamp now but in futher i do
i can not open youtube site beacuse it was filtered in my country isp.
i try upload it here sir mileslakovic.
thanks for every thing you do.

For full power D200 input voltage must be 1.5V RMS
thanks sir
i try to upload video but can not
my video file size was 250MB for under 2 minets

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.

the sound is very good when out put power was about 50 watt.
i thing my power stage has error
i was used a transformer with + - 25 VDC 3A
