bias gnd connected to -vss
about +vdd: can i connect the input pin lm7812 to +vdd and connect the out put pin lm7812 to + bias ?
what about gnd ? i mean can i connect the input lm7812 to gnd and out put pin lm7812 to +biass ?
thanks friends

hi hadi...
if you use below -+40v the green line connect to amp gnd,

 

[irvynejay]

Hello Hadi
I wonder why you get a lot of problem on this,,have you replace the defective ,,getting dc on output maybe you got problem or short on layout,commonly on tl071 tracks check voltage on 5.6v zener if they are balance,,bias is negative (Vss) reference

sprint layout

Hardi a working one

In part this file SPRINT LAYOUT, ​​that only found in PDF format.

Just came across this other Sprint Layout PCB, upload image I did find.

Hi
this pcb had error
look at the blue mark
104 cap not connected to any vere

Connect it to the ground plane. (102 cap left to it).

no need to redesign

Hi Hadi,

Over current preset point connected to 104 this line should be connect to zener ZD5v6

Hi IRSound
greetings TRY detex audio 2 pair amp with ocp post# 3219 FIRST PICTURE
i used orignal cores which detex audio used 2 cores parallel 2 srx speakers on 2 ohm load
NO ISSUES with amp heatwise and sound
warm regards

Hi andrewlebon.
You can send me the layout you are using the plates?
Thank you.

Hi Andrewlebon ,
Thanks for guides..

yes , i should try it ! but can you tell me about output inductor ? what is the part number , manufacture and where the core originally from ? what is the value if you measured it with lcr meter ?

did you use FDA69N25 ?

Regards,
IRSound

 

[luizcpimenta]

Still to test on 120 volts dc +/- sameerx1
warm regards

Hi andrewlebon.
You can send me the files of smps and amplifier?
Thank you

thanks friends

Well then the PCB of this other part is that if you do not mind. that looks great (DETEX), if it were in sprint layout, or other software would be great, thank you very much in advance to all



Also if they could climb the source information and the delay speakers(off delay)

gates diodes 1N5817/5819

Hi irvinejay,

Why is 1n4148 not suitable? It has a trr of 4ns.
Should the gate diode be a schottky type?

Thanks

 

[ionutzxpo]

Trr 4ns but at 400mA current will heat. 1N5817/5819 has 1A will do just fine or MUR120 the best, low Trr and 1A (this is what i use in my comercial amps)

 

[Deleted member 148505]

Thanks ionutzxpo,

But I think not all 1A is flowing into it because of the parallel resistor.
