GROUP

Hello


Groupbuy can be arranged if there is some intrest, as I can see

@25US$ each PCB, for all to enjoy another class-h amplifier!

 

[FAA]

anyone have the gerber files for the pcb? tnx

That's one big honking toroid, perfect for subwoofers! any links to your website Mr. Kanwar? just wanna see your other (model) amps

I thought switched rails were called class G, not class H.

I thought switched rails were called class G, not class H.

Switching of rails takes place in 2 ways

Switch if linear step =G

Switch if Binary HI-Lo Step =H

 

[Tekko]

And the idea is "dissipation of a 50 watt amp with output of a 500 watt amp" no ?

Btw that is one huge diameter donut right there!!

Is that chassi a stripped down commercial pa amp ?

It means your amp is class G not class H, as par as I know class h is higher efficiency than class G, The advantage of Class G is good sonic than class H, because class H can create much distortion.

It is H because it has Square step HI LO binary waveform not a linear envelope follower like in G.

Class-H will only have higher efficiency when the rails step are more than class-G amp, provided the power output of amplifiers are same.

Class-H and G if 2 step have identical dissipation and which is half of the Class-AB amp of same power.. the chassis is not of any strip down pa amp, its my own chassis and first class-H prototype i made some 5 years back.

 

[Tekko]

Either way it looks pro!

i want to make this amp very quickly
thanking you

Andrew,
Make the PCB first and let me know, will tell you construction details after that.

ok...

I am jonesing to get this PCB from you and any other info on power supply or other protection we also need. Im stoked on your design, and would really like to use it to demo our speakers.... Hit me back and let me know if the PCB is made, I should make it in the US... and some details about the power supply would be great too. I dunno if that toroid is custom or found, or "in stock", but I know I have a lot of parts to gather ASAP.

Thanks ...

sir gud day

do you have a full schematic diagram of this circuit im so interested of this kind of amplifier sir.. thank you i appreaciate it sir.. here is my email address victorinotubo@yahoo.com i am looking forward of it..

You need 2500VA transformer with following winding specs: 85-50-15-0-15-50-85 14A secondary.

This amplifier is has all set of protection like DC Fault, Muting, Shrotcircuit etc.
