Looks like we are 95% sorted on the missing display senario

thanks ray

could run clock dac and decoder off one reg.

undecided at present.

"Gee, more boring DIY'ing. We have a tough life!"

Yeah, but someone has to do it

simon
don't try soldering after too many ails.

you can end up with an interesting circuit but unfortunately it may not work

allan

ps simon, i hope Ray has shed light on your display.

 

[SimontY]

lol! Good one

I'm getting ready to go camping at the moment! But I'll have another little look at it...

In theory it could be a bad joint, not connecting Q853 to RN06, but if you measure directly on Q853's most right pin and there's still 0V..... There's only a few mm. between the two .

Ray.

Morning,

There's a good connection between Q853 and RN06.

Hi guys!

Allan, glad to be of help. Hope your reg-job turns out fine.
Always a hard time when one has to decide these things .

Simon,

If there are no shorts/cracked traces around Q853 it would be my first suspect.
And don't forget to fix that 7918 while you are at it!

Ray.

I'm veroboarding a Xo with a tenlabs clock and planning to build it into my cd67se.

My question is if someone could draw me a picture of how much the benefit will be agaianst the default clock of the cd67se.

My plan is to first build in the new clock, feeding it from the default power supply and maybe later to look into feeding it from a dedicated power supply.

I have drawn you a picture of the benefits.......LMAO

 

[Fidelity Audio]

Seriously though you will see good gains with more control better bass and precise treble.

A power supply benefits further.

ha ha very funny.

great drawing skills

ok, so i will put tentlabs clock in it.

Here's a picture of mine Tent XO, sitting in modelling wax ;-) And it's even the one with the printed spelling error. LOL.

Nice job, avr. What's your first impression on the sound?

And it's even the one with the printed spelling error. LOL.

/avr300

Oh dear, looks like you got one of those cheap chinese rip-off copies....

Ray.

 

[gy21]

Nice pic, thanks for sharing.

It's always nice to get some examples.

Did you follow the layout for the power supply that is on the tentlabs site?

 

[avr300]

Ray: More control, more "silent", darker background. Combined with the LT1361 OPAMP, it plays quite decent. But i'm still waiting for my AD8620. Still need more speed and "ongoing".

And yes, it is from the far east ;-) Could end up as a collectors item.

Gy21: Yes, it is the psu layout of Guido's. One more picture of the unit.

[gy21]

Thanks avr300, my excel vero layout is basically the same, also taking 5 strips. I'm just waiting on the xo clock to arrive at the dealer.

 

[Fidelity Audio]

While we are on the subject of clocks.....

What is the best way to mount the clock for helping it perform better?

On rubber mounts etc.

I may tweek my mounting for the clock if I have the room.

Brent

 

[avr300]

As you can se, I just placed mine i a bit of wax. Then I can still take the board out, without anything stucked to the cabinet sides, I guess you can't ;-) The wax has a nice damping as well.

Ane while we are at the topic, should the clock signal be terminated, by a resistor to ground, at DAC end? Right now, I'm just feeding the DAC at pin 28 and ground at nearest groundpoint (see picture http://www.diyaudio.com/forums/showthread.php?postid=892692#post892692).

Hi avr,

On such short runs it's not needed to terminate. The wavelength of the signal is far bigger than the wire. There's a bit more info here .
