100w to 1000w class ab

[Walkalone]

Too danger if run this circuit with 2SC5200/2SA1943 at max rail (95V).
Datasheet 2SC5200/2SA1943 show they're have 0.45A@100V@DC. +/-95 will get about 800 ~ 900W@4R, equal 15A current load. This impossible with 8 pairs power output transistors.
More than 15 pairs will to do it.

So what is your recommend voltage and transformer ampere to get 1000 watts rms at 2 ohms load thanks..
For P5000, and what is the voltage bias and current.

 

[Walkalone]

Maybe use ON Semi devices to do it. MJL21193/MJL21194.
1000W@2R equal 600W/4R, 350 ~ 400W/8R. The rail is about 85VDC.

 

[yehan]

Thanks...1000watts for 5pair of mjl? What is the maximum ampere of transformer? For P5000 schem.?

 

[wattaniya]

this is a powerful amp. already checked with paudio sd18 inch speaker with folded horn bin.25ampere transformer and 85v dc supply .8 pair 2sc/2sa number trannies.
1500w can get with 25ampere transformer.
more rugged amp.
less heat.

Try DRV134 to get better.

hola como estan soy nuevo en este foro pero llevo mucho tiempo trabajando en esto de los amplificadores me gustaria saber si tiene el pcb de este preamplificador gracias

Gentlemen,

This is an English speaking forum. If you wish to post another language, please translate as well.

Google translate:

"hello how are you i am new to this forum but I've been working on this for a long time amplifiers I wonder if you have this preamp pcb thanks"

 

[mrmay]

excellent schemes

 

[vargasmongo3435]

Looks really interesting this amplifier Yiroshi I like the component alignments, really nice indeed.

hello vargasmongo3435.
have much reason.
I bring in foroselectronica YIROSHI excellent amplifiers.
Too bad he was expelled, but just the few amplifiers that provide very good achievement.
I must say that many are not but if your designs are good Redesigns worth admiring.

preamp

if anybody need this hifi preamp ,sub i will share.

hello how are you, I was watching the photo of this preamp and I'm interested much I would like to know if it is possible to obtain the respective pcb and assembly of this design, I hope early reply thanks

Hi forum friends, I have the layout of the amplifier jbl Megatech Urei 6290, but only I have the layout, one of you will have more information on this amp, or someone can tell me if this driver works well, I Realize the simulation of the same from layout, in multisim 12 and apparently works fine, but I would like to get the schematic of it.
thanks for your comments.

Regards.

Quick work p.c.b. jbl Megatech Urei 6290, I think P.c.b. can easily be designed if one have layout.
