hi all,
pls see the power transformer that will option for diyer.
This power transformer was a 110X2 0~16,0~16 35VA.
his is a isolate power transformers, U will see many use the sonfrontier DAC which was made by RS. Since this power trans was expensive in seperate into four chamber of the bobbin. two s pri, two is sec/
All in parallel winding to isolate to lower the noise.
weight of the power trans was approx 550g.
postage increase by USD 5 only. I will groups order with the fcatory so every power trans will USD 8.5 only.
1.5% paypal service.
Groups order will USD 5 +8.5+1.5%=USD13.5~UK pound 7
same as RS this type
PCB mount transformer,30VA 2x24V o/p
RS Stock no. 201-7454
RS price will 11.5 UK Pound.+ postage.
pls check.
pls let me know if U had interest.
from place order to the fcatory to arrived my hand need 12 days.
so I will confirm them before 2006-06-18.
pls let me know if U had interest pls sign up.
thx
thomas

Hi thomas, i not really understand what is the second power transformer. I will go for one that perfect suit with the V3 Dac.

hi Idefixes,
at first i did not search this power transformers fatory so I prepare to call one factory OEM for me, same was isolate power transformers but it hadn't plastic mount for the power trans.
My friend told me this factory's tel no & address that this factory OEM for many overseas company & also had ISO standard. THis is the really isolate power transformers that we need.
as I said, many power transformers had seperate chamber for pri & sec winding. when they winding for power transformers, pri & sec only use one earth ( ground) to seperate the noise. But this is not the best method. If U like more, will seperaste into seversl chamber. every chamber is only
winder pri or sec. The best wa this type, so why RS is selling quite expensive.
there will two chamber in each side.
every side first chamber is pri,
sec chamber is sec.
this is parallel winding & isolate power transformers.
so parallel first chamber pri will 0~110 , 0~110=0~110.
series first chamber pri will 0~110 - 0~110=0`220V
sec winding will be same.
good for DAC, so U can see many hi-end DAC such as sonic frontiers was use this typoe power trans, less noise or said more silent.
for reference.
Actually, I will put it into my version 3 ultimate 1541a for stabdard parts. But ultimate will had 2 power trans for easy side. The USB receiver must seperate power supply to lower noise..
thx

Ok so I sign up for one. Juste confirm the price (I am a little bit confuse) and the paypal email so i can proceed to paiement trough a friend paypal account.
Marc
Marc
hi marc, don't worry for the price, still not confirm, I will count the total weight & post to froum. OK,
As I state that this is a non-profit project. If finally had money remain, U will pay less, OK.
give me some time.
thx

Hi Thomas,
I thought it was the TDA1541A (normal) that u'll be using for this non profit ver.3 ? not R1 if i'm not mistaken
I'm interested at the transformer also let me know the amount needed and i'll pay u via paypal.
Does it means that we can run it with no other additional component since we have the transformer in this kit ? Let me know if anything is missing and i'll need to source for it.

Hi Thomas,
I'm having a difficult time finding a 2x 16V transformer. Would 14V work, or should I go for 18V and use some resistors at the transformer output to lower the voltage.
What is your recommendation? The AC voltage in my house is 120VAC.
Another alternative would be to use 2 smaller transformer with 1x 16V output.
Thanks,

Thanks for the tip.
I was actually thinking more about the 186E16.
http://www.hammondmfg.com/186_187.htm
It's a little cheaper.
Thomas,
The only potential problem with transformers would come if the transformer is pc mounted. In this case we would have to find an equivalent, from Hammond for example, since this company is represented all accross North America. The pin out has to be identical to fit in.
If we do not find an equivalent, it could be necessary to purchase the transformers from You.
Since we have no information on the implementation of transformers yet, we will rely on you to tell us.
Other important points to keep in mind is that, in North America, the ac voltage is 110-120 volts and frequency is 60hz. This difers from the europeen standards greatly.
It is necessary to have two windings on the primary to accomodate both the europeen and american standards. As far as frequency is concerned, if the transformer is designed for 50hz, it should work just fine here.
You probably thought of that a long time ago, but I just want to clarify and make sure we are all heading in the same dirrection.
Thank you,
Jean-Charles

Hi Thomas,
Can I join the group buy for an assembled DAC and a CD-rom controller or is it too late.

hi all,
I was go to china to check the conditions. will update today.
hi dine1967, will never late, I prepare several sets more already, pls confirm asap what U like to join, DAC + cd-rom control kit right. Post together can save some money because of double count postage.
pls let me know asap.
thx

Hi, Thomas
Any update on the USB->S/Pdif converter boards? is 25USD the final price when sold together with the DAC? Also whats the power requirements for the USB->S/Pdif converter board and power requirements for the CD controller kit?
If everythings OK, How much should i send you for a USB->S/Pdif converter board + transformer for the DAC?
Thx, Drew

Hi Thomas,
If I'm not too late, I'd like to order one for myself.
I'd like one with CS8414 and CMedia USB controller.
I'm wondering if you could help answer a couple questions?
1. Is this an improvement of the version 2?
2. Does the DAC come with 2 TDA1541A? Are they matched?
3. Is the CMedia USB transceiver CM106L known to work with Mac OS X? Can't seem to find any confirmation at on the web. However, CMedia website does mention other chips such as CM103+ works with Mac OS X without additional driver.
Thanks!

Thomas,
You will receive a payment for $23 US to add a CD controler to my order.
I returned to the older posts and I found all the information there.
Please tell me if you received the money and if all is correct.
Thank you again

Hi thomas,
any news on the transformer ? how much will it cost ?
if i get this transformer + the DAC v3 kits + cd rom kit... wat else do i need ?
btw, wat's the voltage rating for the cd rom kit ?

hi Dine1967,
If U still had interest, pls confir the payment asap.
hi Jean-Charles,
I ask for another power transformers factory. Its oriental Hi-B, Z-11 nippon steel lamination. pri was 0~110 or 0~220.
sec was 16~0~16 which seperate winding in two chamber. So it means willbe a islate power ransformers. price he charge to me will USD 15.5 per one. 40VA. mainly was the weight, DAC + power trans will approx 3Kg. increase posatge will Be USD 10. Pls considerate that U liike or not.
50 or 60Hz pls confirm to me when U order.
Hi Drew.J.K,
the cheap versio wll had TTL for CD-com, BNC, Optical & RCA input.
the special signal selection board which cobline with the USB receiver was design for the ultimate ver.3 154a & coming full parallel 1865 & 1541a, or other coming uase to save some mpney for diyers.
Pls understand this selection oard had fully use made in Japan relay, 8 pcs per board. ( USD 2.7 per one) two Nano pulse trans because the XLR input was real balance input so it must seperate
from the others input such as rca , bnc.
another questions was the US receiver was
seperate power supply , it means must use another 0~9v power rans if USB receiver use back the power supply as the PCM2706 US receiver in market. There will cause many noise by the switch mode power supply.
pls consent.
hi InfinityPWS pls check the detail.
Hi bro, U right, fully support the Mac & windows so wh this Cmedia expensive that PCM2706 but I still choose it. I need the best, Diyers too.
Hi, all.
Pls check the conditio of the dac in factory.
thx
