Sorry guys but for once i can post in France on this forum !

Bonjour Jules,
envoye un mail à Zanash. C'est ce que j'ai fait et il m'a envoyé 2 ou 3 "trucs" à faire avant de continuer plus loin.

Translation ('coze you want to kill me w/out it :

Hi Jules,
send an email to Zanash. It's what i did and he sent me back 2 or 3 "things" to do before going further.

But i think i won't work more on it 'coze i bought a DAC (Northstar M192) and need only the coax output.

hi zanash,

breizheau send me by mail some pics.

"componentcd5001.doc"
on the signal path, yellow blocks (resistors) are to be changed or is this not critical ?
and the blue blue blocks (caps near the opamps) ? what about changing them ?

"layoutmods06"
what is the meaning for the drawing in red next to the 4700ùF caps ?

thanks

They will affect the sound .....I like dale vishay rn55 as a low cost solution.... but if your going to add good sockets you can take the signal off board from the dc blocking caps ...

zanash,

could you please mail me the whole files you have about all the cd5001 tweaks (with values if possible) ?

thanks

[zanash]

I'll see what I can do.....

the pics are from....a "how to mod the cd500x" booklet that I intended to put together ..but as always things have got in the way.

hello zanash (and others),

as you probably understood, i m a beginner in tweaking. I only build or modified some pairs of speakers.

I also have the project to tweak my marantz pm7200 amplifier and need some ideas. I didn't open it to see what's inside, but I think of putting Schottky diodes, increasing values of the supply caps (12000ùF seems to be a little weak for a 2*25 watts class A amplifier). what else ???

thanks

hello

i change yesterday the output caps with wima mks 4.7ùF 50v. they had nothing better such as black gate in the shop, and i ordered 2 opa2604 for next week.

mute circuit i removed.

sound is already differrent. i only let cd player for 3 hours since changes have been made and my kids (that means noise...) were there. I will try today to have a quiet moment to listen with care and tell you.

bye

I've had a quick look at the service manual of the pm7200 its already got 11eqs10 diodes these from the data sheet are schottky's....
