Aleph-X builder's thread. - Page 120

Hi,

the 2.2mH would be enough. You could probably even go for the 3.3mH but I don´t think this is necessary.
You can have a look with PSUdesigner to see what the difference would be.

I´m not shure if they are easy to buy in France. Just try. If it doesn´t work I could order them and sent them to you but this would cost twice the postal fees......

Be shure to use the right values for the impedance of the caps and transformer. If you want I could sent you the file from my Aleph-X psu.

Thanks,
I will try to buy it.
You can send me your Aleph-X psu file.

What do you want to say when you're talking about the impedance of the caps ?
the ESR ?

wuffwaff · 29th December 2006, 09:06 PM

Hi,

yes the ESR.

I´ve attached the PSU file.

I've found this :
http://www.riviera-acoustics.com/cat...11&language=en

It's a 2.2mH HQ-Ferrite Core Inductor 2.01mm² with
an impedance of 0.1Ohm.

Is it correct ?

(Thanks for your PSU file)

Hi,

I´m not shure these work. It is important that the saturation current is high enough. The Torobars have one over 10A.
You must look at the intertechnik site for more technical details.

Emeric · 29th December 2006, 09:39 PM

I see.

Is it this one you advise :

wuffwaff · 29th December 2006, 09:52 PM

yes,

that´s the one. I just had a look myself but this is the only coil they spec the saturation current (11,7A) for (in the german pdf).

I know I looked quite a long time before I bought them.

William

just found the value for the HQ58 in their catalogue: 6.98A

This could be enough although I don´t think they specify for DC current.

Emeric · 29th December 2006, 10:31 PM

I not shure it will be work very well with the HQ58.
it's all i've found in france.

HI
I would like to ask for help from those who also used the Kristijan type pc boards for the Aleph X .
I'm in the proces to put these the amp together , I already have the transformer , I put together the heatsinks , I populated the pc boards . Just I have to mount the transistors , mosfets and ready to fire it up .
I would like to know wich transistors , mosfets must be matched using the Kristijan boards , and how close to match .
Thanks
Regards

why don't you ask Kristijan?
