Hi, I was seeing the project on the page elcircuit.com; I looked at the diagram and the resistors that go from the bottom are 47R 5W? or 470R? It seems to me that 470R is a very high value! on the site it says it is 470R 2W, but in the diagram it says 47R, and you in the video, what value did you put?
Not sure but it looks like it’s clipping before it reaches maximum volume... is it because of the dummy load perhaps, as the speaker would oscillate in sync with the signal... or it’s just highs in the signal?!
The transistors should be soldered AFTER mounting - over time the stresses will cause problems. There is some serous problem in the driving of the lower half cycle that needs looking into. All credit to you for your effort.
Probably the upper half cycle, too. Only, we can't see it. The modulation is probably from the SMPS. Anyway, I wouldn't call that good quality. But, depending on the music you listen to, you may not be able to notice it. - - The transistors: maybe solder first one leg, the mount, then solder the other two.
I used the gerber files and I have build one module. It works. But I compared the schematic with the PCB, it has several mistakes. Can you share also the correct schematic?
I have a problem, this amplifier does not work correctly. idle everything is OK. but after attaching a load, self-excitation occurs and the current of the transistors increases. I test with the lamp on the primary winding. do you have Idea, what to change??
Hi sorry for interrupting,may I know have u completely done this board bcz I have some confusion also few parts is as written on board is different ,can u send me the pic of your pcb board and the parts list ?u can email to me zainjutt862@gmail.com thanks
@@samsung1461 Hello, thanks to you for your collaboration, your interruption does not bother at all, on the contrary, it serves everyone, with respect to the plate I did not send it to manufacture yet, but I was seeing the clarifications on the page and that is why I had asked Eko.
Arată foarte bine lucrat,100☆,din partea mea,deunde pot cumpara un astfel de radiator si cît costă,sunt din România,cu stimă și respect,aștept răspunsul,dumneavoastră.
Congratulations my friend, very nice job. Besides the amp that is very interesting, I noticed a power supply , I suppose is "switched-mode power supply ". Can you make available the power supply diagram and layouts? How many volts and ampers can it deliver? Using this power supply instead of linear ones, presented you any problems? Sorry for too many questions. And before I forget, thanks for your hard job making both the circuit and the footage. Best regards from Eduardo - Brazil.

bro 1 question bro I make 14 transistor (1943,7 5200,7) +,two channel total 32 transistors but bro u said 1943 maximum Amps 16A then totally how much amps I can give to get 1500watts+1500watts super performance bro now I make 58/0/58 voltage 16A transformer I make ,it can handle around 3500watts ,bro need more amps or it OK,and I give 22000/100v cap/4, 15000/100v cap -4 is it correct bro
Fajny projekt, ale w ten sposób nie montuj tranzystorów do radiatora, lepiej montować na środku radiatora, wtedy jest lepsze odprowadzanie ciepła. U siebie do holtona na 5 parach tranzystorów użyłem trafa toroidalnego o mocy 1.5kVA.
berhubung comen di vidionua g di beles". aku komen di vidio yg ini aja. layout pcb power yamaha yang pisah sama pcb tr final kok g ada di deskripsinya.
there is something seriously wrong with this amplifier, the carrier at 10:32 is really bad, this is can be one of many issues. - comparator circuit needs to be tested independently to determine asymmetrical output. - voltage control loop needs to adjusted, use a simulator. - the switching frequency is way to high. - the integrator is not differential, single ended and coupling in ground noise from the computer's sound card. good attempt but your designs might sound like they working but that waveform looks really bad and should be a cause of concern. EMI, random amplifier destruction.

Nice build! It seems to oscillate on peaks. Try adding a little LC buffering for the driver transistors.
Not sure but it looks like it’s clipping before it reaches maximum volume... is it because of the dummy load perhaps, as the speaker would oscillate in sync with the signal... or it’s just highs in the signal?!
You built a tweeter killer there :)
Look at that HF instability in the peaks... wow
The transistors should be soldered AFTER mounting - over time the stresses will cause problems. There is some serous problem in the driving of the lower half cycle that needs looking into.
All credit to you for your effort.
Cause transstors is need to be adjustmen into heatsink so im soldered first. Thanks for your suggestion.

Bisa di tandai pake spidol dulu baru di bor mas
Okay
I used the gerber files and I have build one module. It works. But I compared the schematic with the PCB, it has several mistakes. Can you share also the correct schematic?
Waw.. Emang racun satu ini 😂😂 keren.. Salam satu hobby 👍👍👍👍👍👍👍👍👍👍👍
Mas mau tanya kalo smps 12 volt di seri jadi 24 volt dan yang tengah kan ct, itu gak papa kah mas buat ct/ground ke ocl terimakasih 🙏
Cool desgn! But isn't there a lot of heat produced by the hi wattage resistors? Wouldnt it be recomended to lift them off the PCB?
Thanks for suggestion
Jika output an powernya di jadikan satu spekaer bisa ndak mas, kena0a ndak dijadikan satu mas powerr nya jadi ndak usah pisah pisah gitu
Got a high frequency oscillation on the negative half cycle that you need to sort out. Loop stability problem I reckon.
Thanks for suggestion its my first ver. Will be updated soon
Sir 1200w ki complete amplifier yiroshi crown kit order karna hai please help
the boards looks gorgeous, i will try some in pcbway. thx, bro, your videos always great.
I have u done this board
I have a problem, this amplifier does not work correctly. idle everything is OK. but after attaching a load, self-excitation occurs and the current of the transistors increases. I test with the lamp on the primary winding.
do you have Idea, what to change??
I have same problem
Remove the 4148 diode it's will fine but bias going to higher ...
May I know u have fond out the solution or not ???? I'm still in trouble
Mr romadhon greetings from india what is the output of each board
Mas proyek terbaru dari power amplifier yirosi crown 2.1sudah di bikin apa belum. Wes take sabar ngenteni iki
can you help me with the component list
I already cleared the doubt by pausing the video at 4:12; you put 10R 5W resistors, is that correct?
Hi sorry for interrupting,may I know have u completely done this board bcz I have some confusion also few parts is as written on board is different ,can u send me the pic of your pcb board and the parts list ?u can email to me zainjutt862@gmail.com thanks
