Nicely done Kari!!!!!!!! Well worth the wait!

Kari, on the output boards, will the screw hole in the FET clear the edge of the PC Board if your laying the FETs flat on to a Heat Sink?

Thanks for the BOM, Kari. If using the drv boards, is this
still the BOM to use, or does any resistor values change?
Not sure if this BOM is for 1 output fet, or 3 fets as on the DRV boards.
Thanks a lot Kari.

Steen.
Kari
Hi,
everything is the same exept the 3W resistors (You can choose a other value). I recommend to use the AX excel sheet.

/Kari
jajabin
Hi Kari,

Thanks for the list. Good job.
Time for shopping

Wing
Loris
Time for shopping ???

The Wiki page says that boards are in manufacturing process, I suppose Kari is not keeping orders any more.:bawling: Otherwise, please correct me I also need some (8+).

Bye
jajabin
Shopping for board components. Not the PCB.
Because Kari posted the BOM........

I have placed the pcb order already.
Can't help you about the board, sorry.

Again.
GOOD JOB KARI
Kari

Hello Kari,

My boards have arrived and they're in great shape. You have done some fine work here. Thank you for all of your effort.

As I am digging into this whole project, now that it is in my face what I have gotten into. What are the correct values of the resistors on the driver boards?

Also I have found multiple schematics in various places, but none match the values and naming that are on the boards and stuffing list. Is there one that matches out there?

Thanks,

Dave
kilowattski
Go to Kristijan's Web Page for the schematic used for these boards. If you compare the schematic from Hifizen's group buy, it is easy to figure out. I have attached the schematic from Hifizen's PCB.

Hi Kari

Got the boards. Good job.

Anyone else still waiting?

Thanks,

Im sure Im way too late, but if theres any leftovers Id like 2 main boards and 8 driver boards pretty please.

Thanks Kari, finally got the boards today.

:)
Kari
Now everybody should got their boards. Phew. If someone is interested i have 10 mainboards and 38 driverboards left. First come first serve.

Thx,

Hi there Kari

I would be interested in a set of boards for a 100w per channel x. However many pcbs I need. Please contact me with payment details etc.
regards
dave
Kari
6 mainboards and 10 driverboards still left.

/Kari
Assesears
I would be interested in x2 main and x8 driver boards if there are any left.

Cheers Bruce

Me too me too.

Hi Kari,

I would very much like to order 2 mains boards if that's possible?

greetings,
Thijs
Kari
All boards are sold.

Thx,

Kari
pinkmouse
I am trying to rationalise my projects queue at the moment, and it means I have 6 extra AX pcbs from the first group buy spare. I don't really want cash for them, but I would trade them for bits to build other stuff, like bosoz components for example. Mail me if you're interested.
PWatts
Hi guys,

Given the huge success of Kari's boards, would there be any interest in perhaps starting a new groupbuy? I can understand if Kari would prefer not to manage it again, but certainly someone else would. A lot of us have missed out on the 1st two buys, and would like to kick in on a next one.

Any takers? I would be able to have the boards made in SA, but local production cost would probably be higher than in Europe or the USA.

Pierre
Francis_Vaughan
Funny you should ask, but yes.

I am relatively new to looking into this, and rather peeved about missing both buys. They seem to be astoundingly popular.

I'm toying with a mix of ideas - all rather over the top - including 4 way active, and also wishing to play with a headphone amp (for my HD 650s - so balanced is nice.)

But I fear that there are a large number of competing thoughts on what constitutes a good board design. Whether to use an existing one, or to continue to refine.

But the short answer is "yes."
Eric
Hi Everyone,

Is anyone interested in a nice set of heat sinks to go with those Aleph-X boards? I have a thread in the group buys forum where I am trying to determine the interest level in KL-271 heatsinks from Seifert that are rated 0.18c/w each.

Details are here
Sander
Hi,

A few months ago I've sold my Aleph X boards from Kari on this forum, because it felt like I coudn't find the time and money to build one. Now I have the time and parts and I regret I've sold them. Is there anyone who's not going to use his Alph boards willing to sell them to me? Thanks in advance. :)
DJNUBZ
if anyone has the boards for this amp and wants to sell them please email me.
Luke
Im still interested in a pair.
ghammond
I would also be very interested in a pair.

Grant.
rjkdivin
Yes.....if another group buy is organized for the boards, I would be interested in a stereo set including outputs.

Robert
Tarasque
count me in for some boards as well.
Loris
Hi Guys I missed the first GB too, and I would be very inbterested in a second one.
hifryer
Im interested in boards also.

What can I do??

Thanks

Check out this thread for compact Aleph-X boards by Bruno. I believe he may have some left.
