Some tracks I play seem to skip or the Singer seems to hasten
Why? Laser on the last leg?
Thanks for enlightening
Hi Brent

Please throw some light

Ben I doubt the skipping is down to that bg nx. I was using 470uf fk there without issue. Have you got another 63 available to swap transports???

Thats exactly how I started my collection lmao!!!!

I found 8V regs caused minor skipping issues.

Have I tried the switch? I have seen it and discounted it as being of no interest to me!!!. Oh bother, I have seriously missed a trick! Will try it later.

Thanks once again guys.

Rob.

I removed my switch to make room for big smoothers.

I just got home to find my Tentlabs oscillators waiting for me! I know what I'm going to be doing this weekend. I've got to read up on this buffered output malarkey, as I've got no idea what that means...

Hey Brent, I had the NX there before and it was skipping, so I replaced it with a 47uF FK and the skipping seemed to go away... then I put it back and got the skipping again... hence my conclusion. I'm powering the chip with a LM317 reg I built myself - perhaps it's the fault of the reg? I do have another transport I can try, and a new laser ready to fit if I can only get hold of the right kind of screwdriver.

Edit: I'm a bit hesitant to move forward with the clocks, what with the skipping, mains humming and no display for debugging... :-/

Hi Ben,

Great, finally some XO's to tinker with .

The skipping can be caused by the combo cap + reg. If the impedance of the cap at the output of the regulator is too low (too low ESR), it may oscillate. Normally, there's a 4.7 ohm series resistor or inductor in the supply line, that provides damping.

So depending on the type of reg and the cap, the results may vary. Bigger caps are not always better. Read here.

I fitted my DAC clock. It worked first time. It sounds wonderful! The difference is immediately obvious, even from cold. Thanks Ray and Brent for making this amazing mod accessible to lazy newbies like me! :-)
