pls someone tell me this layout is correct or not?

pls comment for this amp.

 

[Tekko]

Its impossible to tell if a layout is correct without the schematic to go with it.

detex audio not provide the schematic only layouts.

 

[MatthewS]

Good thing they included a part value screen then..

Could always draw a schematic up by hand tracing out the paths and parts. Fun times

thanks diy members for the comments.

 

[wattaniya]

i compare with these layouts and some path errors in irs1500,irs3000,irs4k5 images, can someone clarify that.

have use pcb and not working, have made new pcb with my layout software

How does a amplifier generating power levels in the access of 3k get away with a single layer PCB?

 

[Tekko]

They don't, the ratings are grossly overrated as well as beeing a oneshot few millisecond pulse into the absolute minimum allowed load impedance using a lab power supply rather than a real power supply.

isn't this refereed to burst testing .

 

[Tekko]

Yeah, and the burst tests are usually what manufacturers use as the power specs just to make their producs look better than they are.

hi nazir
i have made the ir900 and the ir4k5 both work but you have to be extra careful when soldering ,because the tracks are small.
i haven't tried the ir3000 but there are a lot of complains from diyers.

i would recommend you go with manoj,s aud600 it is powerfull and many diyers have build it including me

hi
i have made IRS300 and it work nicely

i use 6k8 as Rss and test it with duble 60 & 75.
is 6k8 right resistance for this voltage ?
how can I know how much must use per diferent voltage ?

i can't find orginal mosfets then i use IRFP250
hef4049 Instead cd4049

 

[herimanana]

hi there,.

could please tel me what means OSC ? RFB ? OCP ? in the PCB layout of irs3000D ??

 

[radokely]

oCp means overcurrent protection...rfb means resistor feedback it set the gain of the amp

What means by duble 60 & 75

Hi dyrs pls tell me what is function of diode mur 160 connected with pin 6 and 3 of ic irs2110.thanks
