Please feed the clock module with it's own clean supply with a separate transformer. Guido Tent's clock was used by me in these players with great success. Elso Kwak's clock is another one to recommend. Only connect the braid of the coaxial or shielded cable to a ground point nearest to the SAA7220. That way you won't have ground loops and best results.

If you're not used to do this kind of work you can make a drawing before you start how the wiring should be. Take the time and don't close the player after the first mods. Leave it opened and listen for a while. You can always put a cloth over it for dustprotection. Why do I say this ? The screws on both sides will wear out very fast after opening and closing the player several times. Never tighten them too hard, you'll regret it. The material is very soft. It sometimes fails after opening the unit twice.
If you disconnect the connectors of the headphone amp you'll have better sound too ( less cable ) but no output on the headphone plug
It's wise to resolder all joints again with good solder. They look cracked and sometimes they are too. Takes some time but guarantees error free behaviour.

Rainy sunday afternoons are perfect for these jobs. Oops, I forget you're from Italy > no rain

good luck and please tell us the results of your modded CD80,

Jean-Paul

You can tighten the worn screws again with some paper around them. Then again don't tighten them too hard...

When mods are finished you can take the cover and clamp the holes some with a forgot-the-english-name tool. If you do this it is possible to tighten them like nothing happened. Some older CD80's had two kind of copper clad screws. Forget about the shortest types. Newer CD80's had 8 screws of the long type.

They are also a bit responsible for the failure. It's better to find some more of the long ones even if they're not copper clad. They will go in a fresh piece of aluminium and voila; when you clean the display too from the inside your cd80 is like new

Hi Jean,

I saw it from your other post that you do not recommend the NOS mod on the CD80, any reason for this?

Also, do you know the diffrence between the newer CD94 and the CD80?

Thanks.

Just want to thank Jean-Paul for the mods suggestions: OPA627 are great!
and Elso from whom I took the KwakClock which made great improvements.
Now I'm almost gone to sell my "old" CD17kis

I'm glad you tried the recommended mods and liked the improvement ! Unbelievable what a CD80 can do, don't you think ? Sounds better than CD17 to me.

Please try to find an extra laser or a complete CDM 1 for enjoying your cd-player longer

Regards,

Jean-Paul

Yes, really a good player! and also you don't have to disassemble everything to work on it.
I still don't know about cd80 versus cd17, the mods I made are only one day old... I think it will be better in abuot a week

I'm trying but is very very hard to find

Now I'ld try to learn how to make a good and simple output stage with NO feedback...

Default Hi, Jean-Paul

Have you looked into what the big sonic difference is on the old lasers v.s. CDM12.x ?

Is it the mecanics only, or is it the servo / decoder chips do you think?

Would it be possible to control a CDM4.x with new(er) chips?
(or CDM 12.x with older...)
