Two times TDA1541.... Probably fed with differential i2s signals.
Sounds familiar ;->

Seems to have a new clock fitted.

Re-program the Eproms of the DSP and it could be made N-OS..

Think i have a mail from someone who has the service manual.
If you are interested i can search for the mail and ask him.

Looks Great!

a true it yours...?

i see all the elna silmic is replaced by black gates.

and the 2 x 14 decouplin' caps also has been replaced with ?????
that's perhaps the most interesting change - hows the sound before/after...?

this player also uses the cdpro transport unit, but not as topload - marantz build an extremely deluxe drawer mechanisme...smooth!!!!!!

and yes - there's a new clock too...audiocom superclock.

did you dc-couple the player...?

i just love this player

if its for sale i'm buyin'...........

:tongue: :drink: :wave2: :grouphug: :happy1: :happy2: :cloud9:

hi guido, how's your balanced i2s project commin' along...?:)

tone 7th March 2003 05:38 PM

neh! it not mine..cant afford one..:)

those are cerafine shielded with copper foil..are they grounded?

the 2 x 14 decoupling caps was replaced with Blackgates non-polarity caps.Black Gate NX Hi-Q


tbla 7th March 2003 05:50 PM

yes, now i see it - but why change silmic for cerafines....????
how about the sound, and what value are the small black gates (14 decouplings) did the sound improve with those?????:)

My dac is progressing slowly. First, i have to work up north quite a bit, staying in hotels. And second, i am working on my house to get it ready to live in. Takes a lot of time.

As for the dac, the splitting works and also the fifo is working.
Can be seen in the 2 * TDA1541 post from a while back. Working on the connection from cdp to dac at the moment. Have some bus ic's laying around i am going to try.

Lesha is working to get the dig. logic into one chip. Should make things simpler.

This player was a digital dream for me.

But only thing about that player that scares me is a dead laser.

It uses CDM4pro and it is quite heavy to get a new laser pick-up (same as in the plastic CDM4)

It takes me a two years to get two new pick-ups for my Studers that use the same drive as this Marantz.
