Hi,

Is it possible know the value of resistors on out rca ground to ground of chassy on cd7550 grundig?

It is only resistors on board rca out.

Thanks

Hi I've got a Marantz CD63 old version and I read from somewhere that the internal is quite similar to the Philips 104. My player refuses to read a disc. When you hit play, it start spinning the disc and it gets faster and then slow down and stop then nothing happen. You can see that the laser head is moving up and down trying to do something but nothing coming out of it. Have you got any idea what is the problem? Would really like to get it back to work. Also if you could email me a copy of the schematic you have on the CDX that will be really helpful. Thanks in advance. my email address:

I'll happily email you a CD104 schematic BUT the CD63 was based on the earlier Philips CD101. The CD63/101 were top loaders. the marantz version of the CD104 was called the CD34. to add to the confusion the B&O version of the CD104 is the CDX, but B&O re-engineered it as a toploader , even though the 104/CD34 implementation is a drawer loader.

There are good threads on the CD101 here, but the classic fix to 90% of CD104 problems (replacing the griplets) is unnecessary on the CD101. I think the PSU caps are the first starting point , maybe check the regulators too, but lets confirm first which you have.

PS You'll need an Inbox capable of accepting a 12Mb attachment ( your listed one bounces - too big). googlemail can do it and is quite easy to register, even as a one time mail drop

Hi,
Are you sure that a capacitor?
It sounds like a normal resistors with these colors:
Red red red gold silver
But I did not understand the value,
With the tester does not measure

Yes, this is capicitor. I know this solution. You can try 2n2 -10 nF also. Please to look at another Grundig equipment like v7000, v1700, v35 (also similar solution). This is only a part of advanced ground technology in the best product of Grundig.

Hi


wojtek.l is correct, its a capacitor.

They look like resistors and the color band have the same meaning.

In your case :

Red - 2

Red - 2

Red - 2 zeros

Gold- tolerance.

That give 2.200 pF or 2,2 nF as wojtek.l have already told you.

If you still have doubts, inspect with a capacitance meter...

Is like this ( the one in the upper right corner )...

it is very simple: ground RCA > capicitor > chassis
