Terrific, thanks Adamus. I will by the DA101C. There are also 102 and 103 and have differences but I'll buy the 101C as you said.
Does it cost only $ 5,25? very cheap... How many transformer for your DAC? Is it 3? all of them using this DA101C?
Does Andrea recommended it too?
Hi Quang Hao,
did you find any mistakes in the Printing on the PCB?
Are there wrong values or can i just orientate at the
Parts printed on?

it means the unregulated voltage if 348v (recitified from the HT transformer. The regulator is putting out 279v. the heater voltage is 5.99v
Transformer for Power Supply I/V Stage (Anode + Heater)
Part Number:
R80-36 primary (0-110) x 2 /SCN: scondary (260-230-0-230-260)(200mA), 2.5-0-2.5(3A), 3.15-0-3.15) X 2(3A)
For the heater series 2.5+2.5+3.15 (make sure 2.5 and 3.15 are in phase or you will have 1.85V).
Here is the link:

Transformer for Salas Shunt board (you need 2 10VA transformers):
Any 220-240 / 9+9V 10VA transformer (toroidal if possible). You can find it at any electronic parts shop.
I recommend use one 9+9 for Analog +5 and -5 rail and another identical 10VA transformer for +5 Digital
For digital input transformer Murata DA101C available from Farnell $5
Go to page 56 and see my quote. I hope it helps.

Adam,
Please give me your opinion regarding all these polyester caps in parallel with Oscon and near the AD1865 and CS8141. I would prefer MKP instead MKS. I've got some axial polystyrene 33nF to mount vertically. I bought some Vishay BC MKS but I don't feel confident to solder them. I excluded any Wima.
Also those cheap ceramic capacitor seam to work very well in some positions.
What do you recommend?

mkp woul be good, but i would be suprised if you hear the difference. I used mks and would again.
Quanghao... Can you show mine? I'm afraid i give you wrong address
Can you scan it like Patrick for me?
Im in Indonesia....
quanghao, my boards arrived today in good condition. They look great. Many thanks again for arranging to have them made & sending to group buy participants.
Re power transformers, in a previous post andrea suggested the following: LS70-1 (2x15V, 1x12V) & R80-55 (1x250V, 2x9V).
apelizzo, does the Murata DA101C replace, or is it an alternative for the Newava S22083?

Any digital input transformer could be used in this project so also the Murata DA101C and Newava S22083 probably are good.
