Aleph 3 , Alehp-X
 
Hello,

I have a DIY Aleph 3 and I am happy. A friend doubts among building an Aleph 3 or an Aleph-X, me known not to respond him.

:confused:

That you differ do they exist in listens to it?
That power gives this circuit?

Angel,

How much of a DC offset do you have at the speaker terminals? Thanks.

i think he's asking which amp should his friend build, and aleph3 or an alephx...

i think.

Angel,

building the X is a bit more difficult tham building the aleph 3 but I think it is worth it.
There are a few descriptions of the difference in sound between X and Alephon the forum. Here are two I found but there must be more:

keep in mind that an aleph x is more speaker dependant, right?

i was going to build one, until i learned that its not really good to pair it with 4 ohm lower efficiency speakers. so, it depends on how you plan to use it as well.

Robert,

Thats not true, the Aleph X with some component mods can handle 4 ohms nicely although not with alot of headroom.

metalman 4th August 2005 07:22 AM

I agree with kilowattski. The Aleph-X can be customized to suit almost any impedance load. It depends mostly on the number of ouput devices used and the bias current level, although most of us have chosen to optimize our Aleph-X's for operation into 4-8 ohm loads.

wuffwaff 4th August 2005 08:09 AM

in fact all of the things that must be watched (concerning power into different loads) when building an Aleph also have to be watched when building an X.

In both you can set 3 things:

1. Power Supply Voltage
2. Bias
3. Ac-Current-Gain

With these you can make everything you want (as long as your heatsinks are big enough). For the same power output even the dissipation will be equal between X and Aleph.

Hello,

We have proven the Aleph 3, the one has some speakers complicated DIY for this stage.

About 60 W would be needed in class A, and maybe a more universal amplifier.

Thank you for their comments.


Angel.

Hello Angel

60W class A => Aleph 5

Universal class => AKSA or Elektor Milenium SE

Saludos

JC
