Originally the video was about an hour long, but this shorter form is much better, right? Please let me know if someone like to see the 1 hour version)))

Hi, no Sund? Check the outputs direct on the DAC with your oscilloscope. You know, no signal on it, DAC chip overheats? Change the chip. You already verified voltages. If so, track the signal to the opamp and the coupling capacitors. Good luck!! Tschüs!!

Awesome video, thx! Question my DCD-695 (same drive) skips (jumps) during playback but only at the very beginning of a CD. What would you do there, what is the reason for it?

Hi, thanks. I would check the self-calibration fugures, if they are within specs. Pickup defects aside, it may also be the dirty or badly oiled screw rod, that does not allow the pickup head to move to the terminal position. Hard to tell without seeing.
