I'm glad you're all happy with the boards. So far approx. 75 pcs have been sold, I still have 25 left.

After that, they might not be available anymore, (unless I use group buy approach, to generate sales 😉)

 

[Hanzwillem]

Yes, yes! Very happy! 🙂 I can't believe how tiny they are!

As you can see, the case for the A30 is under construction...

 

[mpmarino]

It's a wonder you put it all together so fast, Peter. They look very nice,.,.,.and small

Thanks

Waiting... almost patiently!

Very much looking forward to their arrival. Odd that it takes longer to cross the boarder than to cross the pond.

R8 (?) and R8(*)

I was looking at the schematic for ALEPH30.
I am confused by resistor R8 (R8? and R8*)?? - 2 R8???

On the layout by Peter, R8* was included.
Is it right for me to say that R8? can be omitted?
If so what is the suggested value for R8*

Please advice.

Thanks.

 

[Peter Daniel]

Any of those resistors can be omitted and I included only one.

Those links might be of more help:

A30 boards

Got mine today here in Denmark - looks very nice indeed, but d*** they are small. I find the holes for the resistor spaced to close for normal 1/4 watt - is it the idea that they should be mounted with the legs bended inwards ??

And another thing - is it only me thats needing matched mosfets ?
Mabye an idea for an(other) sales service from someone with the tools and expertice to match devices ?? Would sureley be appreciated ;-)

Thanx for making those boards !

Cheers !
Hans

jleaman is doing a group buy for parts for BrianGT's Mini-Aleph boards. He is doing a kit to make it a Aleph 30 (matched mosfets). I got one of these kits, but I got Peter's boards. There is a wiki for it, or you can email him to see if there are still any kits available (they have not yet shipped).

Re: A30 boards

Those boards were designed with miniature resistors in mind (like Phoenix or Panasonic line, 1/2W, from Digi Key, or Caddocks MK132 and Vishay S102). If you want to use regular resistors, they have to be mounted vertcally, which should not affect anything much, considering rather tight layout.

You could try some of Matthew's. His fet's has a very good reputation for being well matched🙂 You better hurry, I think!http://www.diyaudio.com/forums/showthread.php?s=&postid=622207#post622207

Steen.🙂

 

[Peter Daniel]

I just ordered two sets of mosfets from him as well.

 

[12 Cents]

My boards have just arrived, really cute 😉

Thank you very much, Peter. They look great.

 

[Nelson Pass]

Yes, and thank you very much for the pair you sent me.

Peter, did you get my email? 🙂

Thanks
