Hi Jules,

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 4700F 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 ...

Default a booklet, nice idea...

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 (12000F 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 4.7F 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
