Having just powered up my finished (but uncased) DACEND 2, I notice that L19 (LED connected to pin 28 of the CS8414) is on permanently, even with no input signal. Should this be the case? All six shunt PS's appear to be OK (ie. easily adjusted to precisely 5V). Also, no output signal is detectable when a CD transport is connected. Could this indicate a faulty CS8414?

Any thoughts/comments would be appreciated.

Thanks.

Hi Quangao!
Excuseme if i disturb you too.
I have any question.
Can i use semiconductor diode 1N5819 or 1N5842 for 2A 800V? Excuseme but i dont' understand.
Can i use the four diode for anodic? Or only two without D9 and D11?
In this link i read like this (308 and 309):

DAC-ASH (dac-end 2 up date)

The latest question: is it right the 2SK170 SR?

The dac that i would built is the second "DAC END" not the last of 2011.

Thank you!
Regards.
Antonio.

I'm going to pick up on this project again after a busy year. Haven't manage to get it working yet.

My first question. For the DAC board, all my LED's are flashing and not solid but I'm getting 5v for all of them. Is that normal?

Thanks.

Thanks for your advice. I've replaced the CS8414 & the LED is now on at power up & when there is no SPDIF signal (ie. DAC is idle). When I select PLAY on the CD player (transport), the LED goes out, but there is no output (audio signal) to I/V stage.

I have triple checked placement of all components on the board. Voltages at IC pins are what they should be & the six SS regulators are running at the same temp (barely warm). CS8414, 74HC04 & AD1865NK are good.

Any ideas where I may be going wrong?

Apologies if this isn't the right place to post this query; this thread has gone very quiet..........
