Hi guys,

I am a little bit frustrated getting to work my BuffII Trident combo. It would be great if you could give a hand figuring out why is not working:

.) ferrite beds (L6,L7,L8) unsoldered and uninstalled
.) R4 resistors installed on Tridents
.) 2x Trident 3.3 volts regs installed on each side of the buffalo board, as seen in the pics provided at the Trident webpage here in this website
.) 1x Trident 1,3 volts regs installed in the center of the buffalo board, close the clock, as seen in the pics at the Trident webpage
.) 1 Placid monopolar feeding the Buffalo, I had to change R6 to 5R in order to get more than 450 miliamps. Now it is setup to provide 700 miliamps @ 5,5V, so lots of space availabe

I connect everything, switch on my box and ..... everything lights, as it should, but there is no lock !. The mute led on the buffalo is ON and does not change whenever I start playing music, so I get no sound.

To test the setup I went back to the initial point, desoldering Tridents and installing the ferrite beds and I get music again. What do you recommend me to check and make sure everything is allright ?. I already tested with my multimeter that the Tridents were providing 3,3 and 1,2 volts while installed in the Buffalo.

By the way, I got the Legato 2.0 to work with 2.0V output and sounds gorgeous !! (thank Russ & Barrows for helping me there)

Cheers
Pepe

I think you had L6 and L8 flipped!

L6 which on the edge of 'OUT_L' Buf II board needs the 1.2v Trident. The others need the 3.3v.

Hope this helps,
Milton

glt, Milton and Russ .... thank you very much for your help, you all were absolutely right.

The instructions you provided, and the picture showing the numbered regulators, helped me you put everything in place: the 3.3v Tridents on the 176333 regulators and the 1.2v on the 1763.

Now the Buffalo locks the signal perfectly and my "Gonzalo Rubalcaba"´s CDs never sounded better , it is pure, liquid, absolute joy. You are gonna love the Lagato 2, which I had to mod as well to output 2v .... it sings so gorgeous that I have no words to describe it. Heres is a pic of the beast glowing :



I have to thank you Russ (and Brian as well) for doing such an incredible job making the Buffalo project a reality. You guys really rock, please keep up working on it.

Cheers,
Pepe

There are some blue LEDs that have fairly low Vf. But you are right most will not work here.

Very nice project Pepe!!

I am very pleased that you are enjoying it.

Hi:
I want to install the Trident regs but would like to confirm the orientation before i proceed.
Is it correct to follow the orientation of the Trident regs according to the pictures shown above (posted by and lindamar) as well as shown in the TP Trident page?
Thanks.
