If your mail prigram can send it, i can recieve it.
if not, i could make you an ftp where you could upload the file
I'd be realllllllly hapy!

Onno, i am interested in that mk2 pdf, thanks for offering it. Is it possible to put it on a server somewhere for a few days, and send us a link to it? (That's the way a friend of me does when he wants to send me a larger file.)

Dear Bas
I have send the file.
If you recieved it well, pse put it on your server.
Best regards,
Onno

That would be much appreciated. I could use it too, so now i know where it might be found 😀
TIA
All the best

Might be, but i don't think it's a major crime 😉 . If that was the case, then people at Sharefx.com would be in big trouble 😀
Thanks a lot for helping, and that goes for Onno too.
Best regards

Hi Bernard
Yes CDM's speed comes from the slow servo. CDM2/servo in CD640/660 is a lot faster. And my friend's CD880 plays within about 2 seconds after closing drawer!
Thanks for the pdf Beamnet & Onno.

Then its better for the 2nd 1541 to sit on a small pcb. And not to forget feed a 176.4kHz DEM reclock signal to them too.

Hi Bernhard
I do not see any reason to use separate caps.
And more it works perfect (IMHO !!)
pse explain why you see it differently.
Onno
Strange, but that is part of the attraction of the old philips players. The seem to slowly digest your cd, really think of how to play it best and the begin their sweet sound.....

If I recall correctly, it does increase distortion in low level, I tried to stack 1541 and there was a problem, at least visible on the analyzer.
Bernhard said:
Hi Bernhard
By stacking the 1541 did you stack pin 16 and 17 to ?
Stacking pin 16 and 17 gives with me distorsion.
That's why I used separate clock capacitors of 470p and sync the clocks by 100p between pins 16
What IV did you use after stacking.
I use on the cd304 MKII board the original opamps and schematic
only the resistors between pins 2 and 1 of 1k8 is replaced by 1k.
Not replacing that resistor gives with me distorsion
I have seen in the schematic of the MKII that there is a pull up voltage fed to the input pin 1 (NE5532) via a resistor of 2k7 (etc) coming from an 8 volt regulator(7808).
Do you have any clue why Philips made it that way ?
The only thing I can think of is to put the NE5532 in a higher current offset when there is no output from the dac's at all to get less distorsion and a smoother transient.
I still have to try that out by cutting it.

Pin 1 Word select is also in CD640/660 hooked on PS rail. It has something to do with a DC level on the logic (schmidt-trigger?) input circuitry of 1541. For more info Onno, see also I2S leveler here on diyaudio: http://www.diyaudio.com/forums/showthread.php?postid=366490#post366490

Hi Tubee,
Thanks for replying.
Sorry that I confused you talking about pin 1
In my post about the voltage fed to the input of the NE5532 opamps I mentioned by mistake pin 1 but it is pin 2 from the NE5532's connected to resp pin 6 (AOR) and pin 25 (AOL) from the TDA1541a.

Onno
