well ... calculating the expected power with this or the other way makes some sense but realy do expect an amplifier like that to produce this ammounts of power ( forget 1600 just say 300 ) without any protection ????

if you look to any "big amp" rated above 300W@8R (even the cheapest like behringer ) you will notice that have a million ways top guarantee stability to each and every stage ...
LTP and the all amplifier with LDR
vi limmiters
curent monitors for vas and drivers

so what makes you think that this design can produce all that power safe and durable ???

 

[ostripper]

Its not a sin at all thats the standard way of describing an amps power.

Its 1600watt peak and 1100WRMS.

The same type of hype as PMPO just extended to the RMS rating as well ??

Nice work fotios
Poor PSRR is a problem with many discrete designs, power amps as well as opamps.

Thanks Mooly for your kind words. It is a great honor for me that you accept to get in my friends list. Thanks for this.
You may know that this circuit had designed and simulated with Multisim from the beginning. It was as well a good chance for me, to estimate the possibilities of Multisim. I have to say, that Multisim is a great tool. Its simulation results, represents by 99% the performance of the real module. I may to admit that it was a big surprise to me. First time in my life i did something from simulation directly to pcb drawing with success.

hmmmm my friend fotios ..... how are you man ???? do you manage the sumer heat ??? do you have enough ...hetasink ??? ha ha ha

Aman bre sakis. Etsi kani o kosmos? I missed you. How is going? Ola kala pasa mou? Family? Hope everything its OK.
From heat? I think in hell the weather is more cool.
As from heatsink ... i have in home three Hitachi DC inverter A/C installed, total 46000 BTU. They work from 11.30 AM up to 4.30 AM continuously. And, you know ... ΔΕΗ is coming

Sakis, do you know that i was in sin bin four days? Just today i went out. Good experience the sin bin: free of cost shelter, sleep, food, bath, nova sports, tavli ... do you need anything else?
It should just be careful you don't drop your soap

where does 1100WRMS come from?

800W into 2r0 is a more normal way to specify maximum power output.

RMS is 0.707 * peak output power.

So 1600 *.707= 1100watts RMS.

All assuming a sine wave input.

 

[AndrewT]

800W into 8r0 is equivalent to driving 10Aac using 80Vac into 8r0.
That 10Aac = 14.14Apk and the 80Vac = 113.12Vpk.
Taking these two instantaneous peak values, the instantaneous peak power is indeed 1600Wpk.

10Arms exists.
80Vrms exists.
1100WRMS does not exist in any of these values.

No, the amp works into 2R.

It should be 1600watts peak and 800watts RMS not 1100, I used .707 of power instead of 0.707 of voltage.

 

[AndrewT]

oops, my memory.
Yes, we were talking about 2r0 not 8r0.
But 1100WRMS still does not exist.

 

[regiregi22]

He has calculated the 0.707 of the power, not the voltage. Wich one is the correct way for calculating it?

hi biyiers
greetings my 2.1 amp winding my toroidal primary complete my aluminum cabinet with usb input 2.1 amplifier 300 watts each + 600 watts 2 channels bridged

Excellent work Andrew.
My compliments sir!

[Nrik]

Andrewlebon. That is nice work. I don't think very many makes their own toroids.

 

[eesbiboi]

yeah...i wonder how you made those with your barehands...

 

[dudaindc]

Nice one Andrew - I wish I could wind my own transformers like you did...
