900W H-class PA Amp with Limiter

[0QGS]

Guys is there any substitute for the relay used in this circuit I.e. 24V 16 A relay in terms of Amperes and voltage that I can use because I am unable to find it in India

Well, here are Gerber and Excellon for H900 version 2.1.
Enjoy!

Hello Sale030... may i know what software to use in opening this gerber file.. thanks

You can use 2 relays 24V/8A, 24/10A, or one stereo relay 24V/2x8A, even two stereo relays in parallel 24V/2x5A... Try to find anything on 24V

For the viewing Gerber files, you can use any software which can import Gerber. For example, Sprint Layout

No, inputs are inverted.

mile sir pls chek the post 2952

does anyone have the schematic and PCB from Apex SR 800 or extended PCB from Apex B500 ?
I need a schematic to support +/- 100Vcc

Good day Andrew sins you have experience in APEX H900 in particular power amp i have a question
1. The power supply of protect circuit did you separate it from the main Transformer?
2. Did you put Balance input circuit?
why i am asking this because i am data & experience of many DIYer who made this H CLASS, this my first time to make or assemble an H CLASS power amp i had experience but in simple power amp 100W so please don't get annoyed for my many question k & how is your APEX H900 going?

i need exact replacement fo a diode. her155. i substitute fr series diode not ok. also 1n4934 up to 47 not ok. is there anybody know the replacement please pm me. tia!

hi apex audio, i change my mind now i will build h 900w amplifier but i am very surprise about cost of component because ir 2117 price is about 6 $ and price of 3 pair of 5200 and 1943 is also 6 $ both are genuine.however a good challenge for me now see waht will happen?

 

[rohin]

please some one tell me what is right direction for capacitor because i notice surayadi5417 capacitor are in wrong direction according to pcb layout component guide.

 

[rohin]

i am going with this diagram please apex tell me if any mistake on this.

 

[AndrewT]

I can't find the/any capacitor you have marked.

 

[Valenca]

voltage max per rail (HV)

No, inputs are inverted.

Hi Apex, could explain me something?... About the coletor 2sc5200 / 1943 in H900, when I increase the volume of the amp, the voltage is only 65V and does not reach the HV voltage 120v ??? is that right?

Thanks so !
