CD player static buildup
I have a Dynaco CDV-2 tube output CD player. It builds up what seems to be a
static charge and when I tap the case it discharges. As long as I do it every two or three CDs it's not a problem and doesn't affect the playback otherwise. I've ruled out the tubes and am wondering if anyone has had this problem and what they did to resolve it. I'm close to taking off the cover and wiggling things to look for the obvious. I also have a Dynaco CDV-1 that occasionally drops out for a split second and only does it once every couple of CDs. It's also a minor annoyance and neither really takes away from the enjoyment of listening but these are things that I'd like to get resolved and try to rule out the simple things before paying a tech $$$ to tell me that it's a loose connection. Thank you. Bob Walker www.walker-entertainment.com |

Thank you. Bob Walker www.walker-entertainment.com Static you say? Why do you say static? Static would discharge with an ever so light touch. Is that what is happening? A spark? An audible "tic"? A tap would indicate another thing. Try an insulative stick, like a bit of wood or plastic that is stiff. Tap with that. If that has an effect then it is mechanical, not static electricity. Report back. _-_-bear |

Report back. _-_-bear Static is an assumption based on the scratchy sound that it makes through the speakers and the fact that it builds in intensity the longer that it's left alone and for lack of better words 'discharges' when the case is tapped or bumped and not just touched although it only takes a light tap to clear it. It doesn't discharge through the body but dislodges (for lack of better words) from being bumped. If there's a spark it's inside the case and I only hear noise from the speakers, which sounds just like a static discharge. I can tap it wearing a glove or with a stick and it does the same thing. It takes three or four light taps to clear it and the initial sound is more intense and diminishes quickly with each tap. Whether it's mechanical or electrical the effect is noise and it's a sound very similar to a dirty pot when you spin the control to dislodge the dirt. It only does it when CDs are played and the intensity of the noise varies depending on when I clear it. Sometimes it's light crackle and sometimes it's quite loud and takes four or five taps to clear it. That's the best way that I can describe it. I guess that it's time to take it to a tech.

It's no big deal to give it a couple of light taps when I change a CD and it's just part of the routine. It's less than an annoyance but I was hoping for perfect. Bob W |

If the noise be truly a result "static" electricity, I would suspect there to be a realtionship with respect to the relative humidity in your listening room. Are there any differences in amount of static that you experience under in dryer (winter like) vs. more (summer like) humid conditions? Bob W |

Bob W Perhaps I need to stop using static as a reference and just call it a 'scratchy sound'. I have a nearly identical Dynaco CDP that doesn't do it, although it has it's own annoying issue. To answer your comment about humidity; I live in the SW desert and it's very dry all of the time with very little humidity change throughout the year and static is only an issue with certain fabrics. The conditions haven't changed in the house for almost 10 years and I've had dozens of CDPs and DVDPs over the years on this system and have never had this problem although these are my first tube output CDPs. However, I understand what you mean from living in climates where static is an issue when the air gets dryer. I really do appreciate all of the comments and advice but I think that it's time to take it to a tech. Bob Walker |

Bob W You have a mechanically based electronic intermittent. Probably a bad solder joint or connector. Based on your present description. IF the sound is in both channels then it is in the PS or somewhere in the digital path, probably in a power supply lead, although that's not 100% certain. _-_-bear |
