Hi
My friend purchased a B3 insted of a B3SE by a misstake,
The solution now is to set the B3 in Stereo mode for stereo use.
There is no room for a sidecar or other extension cards so the Wawe Io need to be wired directly to B III
The source is a Wave Io directly wired to the B3 bord sending out I2S
All the steps in the Integration Guide for stereo operation has been performed but still no sound or lock light.
The wave io is working and playing music when tested on another B3SE.
I have placed the jumpers : JPCM1 JPCM2 and JPCM3 and placed the twelve jumpers J1-J12
I have set the SW2
I have good power in and out of all all tridents and 5.2v in on the B3.
Still no lock lock light or music.
Suggestions?

AVCC modulle removed for visual
This is a temp setup but worked perfect on my other B3SE
Will cleanup when things are working

That looks okay so far (assuming the WaveIO connections are correct - can't really see them).
Try adjusting the DPLL Bandwidth to the highest setting (SW1: 5, 6, and 7 to OFF).
Note: You need AVCC installed again for the board to lock.

Tested SW1 5 6 & 7 to off
SW2 8 both off and on
nu luck..

Possible fault found,
On my working B3se the 1,2v trident sits at right
side ( when looking from top and power inn against me)
It is oposite om the non working B3.
Will switch soon,
Ideas if the 3,3v would have hurt the Buffalo 😶?

That would definitely keep it from working 🙂
As for damage, you will probably be okay, but I can't promise that. I have seen reversed Tridents before without damage.
Back again,
My bad, i was looking from the other end, the left become right....
The Tridens where at its correct pos and outputting the apropriate 1,2v and 3,3v.
The AVCC is outputing 3,5 at both channels.
The R4 for the 1,3v VDD is quite hot though.
it is a 1/4w thru hole resistor,
can hold my finger on it but it is not plesant.
Whitout doubt mutch warmer than the other R4 resistors.
Hmm..

Lower side:
Do the firmware contribute in any way regarding this probl?
The B3 is from 2013 ish.
Can i possibbly use the firware from the B3SE or opposite to test if the firmware has a bug?

The firmware should not have any impact. In fact, you can experiment by removing the firmware chip to se sure. It will not have all the internal mappings etc, but it should function without it.
When/where was this Buffalo purchased?

Hi Brian.
I'm the friend that pellesmil is helping regarding the B3 problems.
I purchased the B3 from Twisted Pear Audio sometime between september and november 2011.
After to long time in a drawer, I will now try to finish my project, and looking forward to success with help from you!

Maybe your problem is with reversed dip positions. Early iterations of BIII have reversed settings than in users manual...
Looking at fantastic Leonvb manual there is on page 24 DIP switch settings
Also paragraph about new vs old and recomended settings
Double check it maybe that is your problem

Tried the inverted switch both SW1 and SW2 and only SW2.
No luck....
Have also connected individual earth for DCK D1 an D2...
Still quiet

After a lot of help from gwikse on a "sister forum" in Norway he came up with the idea of tracing power to the Crystec.
After some initial measurements the Lock light lit for first time 😀 😀 😀
But how long was Adam in paradise....
The light went out after i touched the Chrystek.
After some investigation and check of the soldering i found out that the light goes on when pressing on right lower / nearest corner and goes dead when pressing on the left lower / nearest corner (this is when looking at the B3 with the PS down and the text the right way.
There is a low qlick sound (relay) when the light goes on and off.
What do you think, qould this be reapaired by means of my soldering iron (not by far the smallest compaired with thise parts ?........

I have been trying to assist pellesmil with troubleshooting his dac. He and I believe the crystek clock is damaged. He tried to figure it out on his own with a little assistance from me. And now he needs your input on how to proceed.
The clock is damaged. I do not know if there are other problems as well. And prior to swapping the crystek I though perhaps it would be a good idea to verify that the B3 is working if the clock is swapped out without actually swapping it out.
He has a working B3se that AFAIK can be used for this. If I am not mistaken, he can connect both the B3 and the B3se to the I2S source and connect the clock pins from the healthy B3se clock output to the corresponding header on the B3 and leave out the trident on the B3? If all else is ok, the B3 should lock as well as the B3se right?
BUT. The picture he posted of the clock and the "5V" on the crystek output pin worry me. How is this possible? Where does the 5V come from? Is it related to the trident that power the crystek and eliminated as a possible issue if he remove the trident? Is this a sign of a damaged ESS chip? Is this just a matter of a Vin to Vout short on the trident or something like that?
Well, my suggestion is that he remove the trident. Measure the pin again, if there is still 5V there, well what then? Is it supposed to be like that? Come on. Fumbling around in the dark here....

Sorry for our slow replies. Russ and I have both been slammed at out day jobs lately.
First, yes, that plan should work. Thanks for helping out.
Secondly, the 5V is troubling. There is no 5V anywhere near the XO. That is a GND pin, so I am guessing it was a mistaken measurement from the 5V input to the XO GND. If not, something very strange is happening.
