I'm supposed to be working!

And unlike some people, *ahem*, I don't have a soldering iron, workbench and extensive test equipment in my office!

Hm, i'm supposed to be working too, but I don't have a job right now....

But don't worry about that, it leaves me plenty of time to play with other things

Hi there..

Just bought one of these giant machines - a standard 63' for $30. Guess that's ok.

The only problem is some kind of oscillation, mechanically, in the transport. It can be heard if I press pause and I'm on track 1 or 2. If I'm on one of the last tracks, I can't hear it. It's round 500Hz.

When the CDP is cold the sound is worst. It also skips when it's cold, but only when it's cold. I have done the drive cleaning, both the optics and the mechanics.

If I touch the steel rod guiding the laser with the tip of a small screwdriver (through the small square hole in top of the transport) the sound disapers. Wheter this cures the skipping I don't know.

"Leave it on" your might say, hmm, but what's causing the problem?

Scince there's nothing to ajust beside laser power, I'm wondering - is it a worn out transport?

Anyone?

having repaired hundreds of marantz and philips with this cdm12 transport I can at least cure one problem now.

Remove the transport from the mech, now remove the laser.
Clean off all the white grease(probably now yellow, and if it is yellow thats bad) from everywhere including the laser.

These players suffer from that grease getting hard, it softens with heat so that probably why it skips from cold (laser can not track properly with the hard grease).

The really yellow/orange grease is caused by smoke.

Touching the guide bar should not cause or stop hum.

Check every earth in the player etc.

$30 is good not even considering you can make this a really good player.

Just a note to say this player is now unbelievable. I am amazed.

It must be putting out at least £600 sound quality lol.

I can hear everything. Im sure I can hear Christina Aguilera playing with her self on Impossible. lol

Would that noise be caused by the servo then, that's trying to 'drag' the pickup through the grease?

Ray.

You dirty rascal!

Pls. don't

in the player...

It is a possibility the servo is strugling with the laser.

It certainly wont help.

But if noise like hum can be heard and when touching metal parts either helps or makes the noise worse its usually some kind of earth/ground problem.

Ground is very important especially in audio, one of the reasons KI stuff has a copper chassis
