Hello Alessandro,

What part of the manual do you need ? It is too big to attach.
If you want to modify your CD 80 please see this thread:

Philips CD80 tray problem?

Regards,

Jean-Paul

The schematic of what Alessandro ? The analog or digital part or do you simply want the whole manual ? Pretty impossible to attach as I stated before. I can attach the part you need most...

Sorry Jean Paul,
I'm just at the beginning of diy and I'm trying to do something with a BIG help of a friend here in Rome.

Is too much to ask for the digital and analog schematic?

If it is, I'ld like to have the analog one as i'ld like to (try) work on it...

Thank you again
alessandro

PS. do you think is better to try to find another CDM1? (I've just take an used CD80)

Sorry Alessandro, I got your mail but didn't have the time to scan the schematics. I will do it when I have some spare time...

Thank you Jean-Paul!
I was afraid for beeing late with my answer some days ago.
I'm not in any hurry...

I've been loking inside the cd80 but I didn't find the IC6522 and 6523...

and, I'm waiting for an answer from people here who seems to have the laser replacement for the CDM1, if you're interested I'll let you know

(always sorry for my english)

Hello Alessandro,

I just sent you something ! Good luck with it and think well before you do something in this player. The mods I did are proven in several CD 80's. I am not claiming wisdom but you can't go wrong with these. It is always possible to go further but it 'll cost more time and money and probably is irreversible ( if you care about that ). Best would be to make a new powerboard that fits on the mounting holes of the old one with better decoupling and LM317/337 and of course a discrete built I/V convertor.
If I would have one myself I would go that far but unfortunately I can't find a not too expensive AND goodlooking example with a good laser. So I mod them for others...

IC 6522 and 6523 are the regulators on the powerboard.

Jean-Paul
