How critical are the Sanyo Os-Con caps? Can't we just use something decent like Panasonic FC's?

[QUOTE=rtd;2074046]There is 3 small area behind the CS8414, the AD1865 and the 74Hcxx but not "wide enough" to form a large groundplane.

It is on the top layer!

You can use L for R 10Ohm!
thank

In the Salas shunt you can use other Cap! with one If you like!

Is there a finalized parts list up yet (BOM)?

Or should we take the parts as shown here: DAC End 2 - the AD1865N-K with single ended vacuum output stage

Thanks

You could, but I would say NO because Oscon is unique (special) cap and is the best for digital signal decoupling. On the analog though you could use something else like Elna Silmic for example.
Oscon SP is best for this purpose then SH.
Oscon SP around 220uF is easy to get from eBay while I cannot find the 47uF SP 16V

Anyone can help to find Oscon 47uF 16V SP series please? I can only find SA

Quanghao,
where did you find 47uF 16V Oscon? Are they SP series?

Farnell got them in stock at $8.00 each !!! Too expensive

The secondary for the filaments should be 8v 3A instead of 9v 1A.

and the 2 x 2.2ohm 3w resistor should be 2.2ohm 5w
