Aleph 5 - identification

[dominique-tanguy]

Dear all,

I am looking for an Aleph 5 on E-Bay. It is a home built version. It is made of two mono blocs and the construction is looking quite good.

http://pages.ebay.com/link/?nav=item.view&alt=web&id=221638402716

I am just wondering about the number of output transistors. I understand from the manual available on internet that each mono bloc should show 6 output Mosfets, and looking to the rails, I count 8...

Could someone help me to clarify this issue?

Thank you in advnce and Merry Christmas!

Cheers,

Dominique

It is working for me... This might be a restriction due to your location. I will try to attach the picture sirectly.

Thank you!

I have seen this one, and tnis is the reason for my question. I see 2x3 IRF244 on the schematic and I have the impression to see 2x4 on the pictures...

It is the Aleph 3 that has 4 x MOS-FETs in the output stage.

The Alephs are all stunning amplifiers, I've got the monster Aleph 4 with 12 x MOS-FETs per channel.

Aleph became state of mind ....

analyze and build your own iteration

important things are rail voltage and not lacking in outputs (number of pairs)

 

[KatieandDad]

All the Alephs, as with all Class A amplifiers, need MASSIVE power supplies.

This amp seems to be a mono block version of aleph 5 , using 8 output mosfets instead the original 6. This is not an issue as far the rails voltage (2x30 v ac) show it is a version of aleph 5. Looks pretty to me!

Merry Christmas to all!

As others have already said, build it how you want it. That is the great thing about the Alephs is their ease of scaling. Mine started as an Aleph 5 and then I added another set of outputs to make an even 8. Here is a link to it. I primarily did it because 6 mosfets didn't divide well onto the 4 heat sinks each of my mono's is built from. The good thing is I have more current available than an Aleph 5 for 4 ohm loads.
