Thanks Helfred.

[schro20]

and another 6 mono kits

an order for a friend (Joshua Adams) who is not on the forum. (Yeah, he's getting a bunch for his family; cool!)

Another pair for me too. I will twist a friends arm to make one. He is a DJ and needs a reference amp... The powered monitors I made him work ok, but not NEARLY as good as this amp.

 

[udailey]

Just a short announcement.
We will ship to you if you are not in the USA. Thats fine and we are glad you are here to share this wonderful amp with us.
Mail will be registered and insured and if there are extra charges associated with your country's import taxes these will obviously be your responsibility.
We need to make sure you get your boards and components and that we can track them if there seems to be some sort of problem getting the mail to you. Group buys need to be safe for everyone involved to work
Thanks guys,
Uriah

We are 1/3rd of the way there !!! We now have 34 requested kits !

If your building monoblocs then these will work fine.

Part # XFM-D0012 from here:

http://www.apexjr.com/miscellaneous.html

100VA is a little small, even for monoblocks. I guess they will work, but you will ideally want something in the 250VA range. Also, 2x24V is the output voltage, but there is some flexibility there (22-25V is okay).

Antek sells a 300VA toroid with a 2x25V output for $36.

Parts Connexion sells stereo Alps pots in 10K, 50K and 100K varieties. Which of these would be suitable for making an integrated amp with this kit?

[udailey]

That toroid will work brilliantly.
You should look for a pot that is somewhere around 20-25k.

I used that transformer for my fist stereo version. It worked VERY well indeed.

However this will be my secondary amp and not my primary reference and will most likely be on small bookshelf speakers so it will loaf along at minimal power.

 

[udailey]

Yeah, I agree the large Anteks are great. I use a 400VA Antek from time to time and with the chipamps it is just incredible how tight everything becomes.
Uriah

 

[troystg]

A true set of mono-blocs with that 300va transformer in each and these boards could VERY well be a reference amp...

Sorry but after building MANY chipamps, Mauro's amp smokes the pants off of them.. But then again it is NOT a chip amp, just as easy to build as one.

 

[Mindcrime]

I"m in for 2 mono kits

 

[udailey]

Thanks Mindcrime! Seems a few people from AZ. Do you guys have a good Audio Club in AZ?

Not that I know of.... I'm just a closet audio junkie I guess? lol

 

[udailey]

nvrgdenuf is in for 4 and maybe 8 depending on when the buy closes. I dont know if he prefers sooner or later. We will see.
Thanks nvrgdenuf.

[xaudiox]

is it possible to order just the PCB? i already have most of the parts..

I'm interested with 4pcs pcb.. thanks

 

[schro20]

just pcb

We can always run additional PCBs. Trick is that the whole thing won't happen unless we get a minimum on both parts *and* boards. Else the economics won't work.

Peter

 

[udailey]

Hi,
Yeah I agree with Peter. I have no problem selling just boards AFTER we get enough orders for parts as well. The cost difference on boards will be minimal but the cost difference on NOT getting 100QTY for all parts will seriously effect the overall cost because so many price breaks are at 100kits.
I already have good pricing for pcbs. However, I just got a house that will give me black boards with gold plating for a good price. We will see at the end of the quote. I have some things to sort with them first but wouldnt that look GREAT!
Black boards Gold traces/pads
Of course right now we are talking green boards white silkscreen.
