Could someone please direct me to a circuit diagram (schematic) for the IV stage power supply (Salas Shunt). It may have been shown somewhere but I seem to have missed it.
Thanks.
Thanks.
R-Core and Center Tap
The R-Core from diyclub is:
R26-29 primary 115 X 2 : 0-9 X 3(0.7A); 9-0-9(0.7A)
It has 3 9V, 0.7A output and a 9V with center tap. I can get two of these for the DAC-End. What's the "center tap" for? How should I connect them? I saw nothing on the Dac-End board for "center tap".

No need to use the centre-tapped 9V winding. Two transformers provide six 9V windings, all that is required for the DAC board.
Just ordered a couple of these myself.

28 pin, 24 pin and 14 pin sockets Help please
Could someone provide links to 28 pin, 24 pin and 14 pin sockets from DigiKey? I wasn't sure which ones are the correct ones.
Thanks a lot!

If we wanted to use a transformer after the I/V resistor inorder to allow a lower I/V resistor (alla AudioNote) can someone recommend a quality transformer part number for this application?
Trimmer Fairchild Semiconductor ?
I couldn't find Trimmer Resistors by Fairchild. Could you provide an alternative? Mouser has many other brands.

Terminal Blocks and Heatsinks
I think Terminal Blocks and Heatsinks are missing from the BOM. Quanghao, could you add these two elements and links?

Why not add the circuit to correct the 13 SDATA offset between channels and reclock with a decent XCO ?
With headphones the delay is noticable.

Hi All,
The five pieces of the Salas multi 9v transformer are out of corrosion control and can be shipped. Please PM me with current address to ship to and I will finalize ship amounts , provide you with a total an a Pay Pal edress to use. The two international units will ship USPS flat rate.

Hi!
you can use this:
Newava Technology S22083
Or Lundahl LL1572, ore pulre...
or better!
Some friend remove it, and they like the sound, you can try do it!
Hi Bud,
don´t know if you just make one for me, I´m still waiting for the answer about the trafo for IV stage and also the trafo for the Phono-pre of Quang Hao.
