Default Clock Cap Value on CD40 Marantz

Hi all

Does anyone have a service manual that may tell me what the value of the two SMD caps on the clock crystal are on this CDP?

Wanna do a quick few mods on a friends player but without going the whole clock route. Will replace caps with silver mica types.


Regards

Hi

Probably 22 or 33 pF. my advise: Don't spend money on the mica's, they won't turn lousy clock electronics into a decent one.......

Default Yes still interested thanks

Hi Guido & Fin

I will not dispute the fact tht a good clock makes a big diff.
However, my friend is not spending real money and I will probably work on his machine for a bottle of reasonable wine....
I probably have some of the silver mica's in my parts bin, they may not make a Tent/Trichord/LC/Kwak clock but they are free to me , a new clock would not be.....

Thanks Fin

Hi,

I understand your point, curious about your results.

I have replaced the clock caps on my Theta Data Basic II and that definately improved things. The Theta clock does not seem std pierce by the way, it seems to use a crystal, transistor , 2 caps of 68 pf I think and 2 caps of 22 pf or something like that.

Myself and a friend both liked the results of changing the ceramic bead jobs to silver mica types......

PS, I have fitted trichord clock 2 to a Marantz CD17 and a Philips CD850 and liked the result a lot. I would rate the silver mica caps at 50-60 % the effect of a trichord clock 2...

Guess some of the clockers out here would rate the trichord at 40-50 % of theirs......

Still leaves me with 25% for free!!!!!

But, silver mica could be a very strong error.
You could simple leave the original caps.They are good enough, and small enough.
Or if you want, but without great difference, you could try ceramic multilayer, smd.
