ReplyDeleteokay brother
DeleteThis comment has been removed by the author.
ReplyDeleteI think you all should not wast your funds the circuit does not work the guy is a very bad. I tried to do this circuit because of the efficiency of class d I think I will stick to my class Ab which has minimum parts and very clear sound.
ReplyDeleteHahaha please dont judge, this class d amp is works. The power is more high than your class ab.
DeleteThe circuit is a scam it doesn't work. All what they say is class d is efficient but to me most class AB on the Internet is far better than this circuit. Like renowned Nelson pass all his article and amplifier are best and sound great.
ReplyDeletewhy you spamming comment lik this. If you cant build class d amp, dont try! its more difficult than your class AB
DeleteI have repair a lot of class D amplifier in my country and believe you me my Nelson pass class AB any mosfet by didik with jfets input sound great. [email protected] is mail box. 😂😂😂😂😂😂
ReplyDeleteits more efficiency this class d
DeleteMay i ask you what efficiency did you succeed with this Class D?
Deleteyou better try it. it's only 25 dollars for the component and share the problems you face here. it will be more helpful for others
ReplyDeletenext i will make a gerber files for this pcb
Deleteamigo puedes pasarme el archivo en proteus?
ReplyDeleteamigo puedes enviarme el archivo en proteus [email protected]
ReplyDelete[email protected]
ReplyDeleteQ2= CD4049
ReplyDeleteQ3= IR2110 not found my Proteus 8.4
you can make it your own design
DeletePlease tell about 12 volt supply. 12 volt negative line is directly connected with line of -55 volt
ReplyDeleteyes its connected with - rails.
DeleteIs it -12volt or 0 volt?.
ReplyDeleteMUR860 is not available in my place. Which diode can I use instead of MUR860? In the PCB there is one MUR860 and one MUR460, but in the assembling video you used two MUR860.
ReplyDeleteThis amp really good. I already make it.
ReplyDeleteIf you make this amp , at first make all ic tester . you can see all ic tester on you tube. Channel name Pranatosh Tech.
I made the amplifier. But when I connected 12v supply to the board, the Ic IR2110 getting over heated and damaged. BD139 and Mosfet also damaged. What will be the problem? Pranathosh how did you give the 12v supply? Is it O-12v or -12v and +12V? Did you use MUR860 diode?
ReplyDeletewhat the diode u using? is there oyu using 12V ?
Deleteuse 0V 12V
0v connected with V- rails power amplifer
and +12v connected to bias voltage
Pranatosh, I watched your You Tube Channel. Now I am going to make all IC tester.
ReplyDeleteI used MUR860(D6),MUR460(D10) Diodes as shown in the PCB. I used 0v 12v for bias voltage as you told. Is there any adjestment for Trim pot (RV1)?
