sekhar
where is your final pcb,
maybe other builder want to try
pcb and component lay out please

 

[engel dela pena]

is this final and working driver pcb?

 

[engel dela pena]

what is happening here?
please somebody help
5200/1943 as driver

Use pcb from B500 for B250 or I can suggest you to build HV350

Dear sir, I will use B500 pcb, and then use 3 pairs of 5200/1943. Is there any modification to the pcb and its components?

Sorry to many question, I am newbie...

 

[aman khalsa]

this pcb is ok..

what is happening here?

nothing is happening my dear i use 5200-1943 as drive because i have no 15032-33.
so u can use 5200-1943 its simple.
nd there is a mistake in pcb i show as a blue line ..make it and enjoy..

which is better hv23/hv25/hv350/b500/apex550w

 

[apexaudio]

which is better hv23/hv25/hv350/b500/apex550w

There is no better amp, just better for you. I suggest http://www.diyaudio.com/forums/solid-state/167394-quasi-amplifier-beginners.html

[Tekko]

I agree.

 

[wattaniya]

which is best 5200/1943 or irfp9240/irfp240?

hi apexaudio
greetings do you have any clipping indicator schematic to share
for your h900 amplifier so we can have visual indication of clipping please can you help out
thanking you

Add LED in series with LED integrited in NSL32, and you have clip/limit indication.

You can build good amplifier with BJTs and with MOSFETs

 

[wattaniya]

anybody have BJTs and with MOSFETs pcbs with aroung 500w pls post.

dear sir apexaudio,

You said that to build B250 I can use B500 PCB. So, what kind of modification to the PCB and component? Some schematic or PCB layout could help...

Thank you
