Marantz Cd84

Hi Elso,

I have read on your KWAK-CLOCK-text.doc this:

"The KWAK-CLOCK will work with any crystal in the range 8 to 24.576 MHz." but Marantz cd-84 had crystal 4 MHz.
It is possible mod your Clock for work at 4MHz?

Bye

Hi Andrea, In fact it will work with the 4MHz crystal but it will not do any good as this clock is probably for system control (U COM). You need to replace the clock feeding the decoder and/or servoproccessor :cool:

Sorry Elso,

here you can see the picture that was on zip file.



These is a great news. Is it necessary do some mods for improve the 4MHz crystal, or just use this crystal on KWAK clock 7?

Thanks a lot

Bye
Andrea

Hi Andrea,
No mods needed for the 4MHz crystal.
