start post no. 1

greetings master apex. how can i get the schematic for h900? its pcb design, parts placement power supply section and all calibrations?

thanks and more power to post more powerful amplifiers...

Connect LED+10k resistor parallel with the MUR1620. It will be no light without signal, but it will flashing if the step driver is working.
I can give the schematic if you need it.

hi sajti can u share the schema thanks.. its owkie i used mur1640 instead of 1620? still waiting for solution..=(

sir sajti is this correct..http://img62.imageshack.us/img62/235/kfwj.jpg

That's fine!

thanks i will try.. my internet sucks.. i delete my previous post..=)

An externally hosted image should be here but it was not working when we last tested it.

hey.. Stay cool sir.. Everting will be fine and success if we cool here 😉.

thanks guys now my h900 is working, i clean the board with lacquer thinner,and test again.. now step up is working .heres my pcb thanks apex😀

Hi Apex,

just a question: Why didn't try the Crest step driver? It's quite simple, use just common components, and cheap.

congrats! you got a good board with clean tinned traces...🙂

Tracking Down Converter (TD class) will be better, and amp will be TD2000 instead H900 🙂

Looks nice. Do You have the full schematics?

Yes, I will share TD2000 in 2014

Waiting for it Apexaudio

Hi Mile , warm greetings from Macedonia , i have experience with audio amplifiers 🙂 Can you send me the full documentation about H900 ? (power supply board , amplifier board PCB layout , circuit and so ) I want to make stereo version of H900 🙂 Also , how much toroidal transformers i will need for this amplifier ? Just for the amplifier .. 2 kW will be enough for the 2 channels ? Maximum AC voltage should be 😕 Will i get maximum power with 2x55V AC 1000VA transformer for one channel or ???

And i still don't know why 4x40VAC ??? can't be done with 2x40VAC ?

And if it is needed 4x40VAC show how to conect the power supply to the amplifier board , sure with the layout pcb 🙂

greeting daniel.
I dont know why u ask that. Everything u ask is here, please read from first page, dont be lazy..

I put together the schematic of TD driver in the simulator, but it's was not succesful, unfortunately...

You must simulate full schematic.

 

[sajti]

You must simulate full schematic.

I will do it, at least tomorrow. I had some idea, how to implement it.
