Gamut amplifier

[jouch]

I'm wondering I some body have some informations about Gamut amplifier.
The construction and circuit seem to be realy easy, they only use two mosfet per channel.
But that's all I know.
Thanks

All I know is that high power MOSFET's modules in a so-called Mini-Bloc (SOT-277) package are used.

The schematic would be rather similar to an upscaled aleph or so, I think...

 

[jouch]

So I suppose I should use the same architecture as one an Aleph, but change the out put stage with this block?
Thanks

Certainly you can give it a try. I have built some
Alephs and Zens with the IR TO-240A packages,
and the 500 watt rating is certainly attractive. They
consist of 4 regular sized power chips arranged in
parallel or series/parallel depending on the part.

However...

These are 10 times more expensive than a single
device at 200 watts, which while not a consideration
for me, (mine were samples) will not be ignored by
most everybody else.

and...

You cannot assume the level of matching of the
parts as it appears that they are intended for
switching applications, where Vgs matching is
not so important.

nevertheless.....

These are cool looking industrial parts, and you'll
be the envy of all your DIY buddies.

What about the Greenwall amplifiers ?
They look like a complete ZEN family ripoff.

greenwall amps

Hallo,

had a close look at the greenwall amps. They are Zen Amps. Look at www.greenwall.de

[Nelson Pass]

They aren't the first. A certain outfit in
North Carolina also plagiarized the Zen.

Zen

And they even have a link to Passlabs on thier site!

M250I, monoblock amplifier that I can make by myself.

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

Thanks

This I know. But I don't know the currently naming of that manufacturer from Germany.

 

[reinhard]

He is out of business,

Are you A. K. on AAA?

Schematics for amplifier the images

Hi ANADIGIT!
If you are unable to insert schematics your audio amplifier (with pictures).
thank you and cheers!!

...... some time ago I have try to layout PCB for this amp , but some resistors wattage are wrong , I have no BOM list , just schematic ...... below PCB

could I use it for my bass guitar

Think you need a JBL scoop for your bass guitar.

Differences in enclosures - 4530 Scoop vs. 4507 JBL?

 

[tinitus]

Think you need a JBL scoop...

thats not an amp or is that a speaker

its OT, but I have a severe problem with out of phase signals from woofer's back and front wave
my ears simply cant take it for very long, or at least not very loud
no sir, sorry, not for me

OT, sorry guys

 

[tinitus]

would still like that amp for bass guitar
