You reason is a capacitor.
You know more information about this special grundig ground?

If you do not know if, in italy many people talk about certain products grundig, saying that playing in a special way.
I repeat not all just a dozen products of a well-specified period.

I'm sure you're right, but I still challenge anyone to detail what this mythical Grundig earthing arrangement is. I would buy a Grundig 7550 if my CD104 broke as I like the simple style of it, so I don't doubt it is a good player. I'd just like to see a picture or schematic which supports this view. I cannot see anything here which isn't 100% Philips but maybe the changes are hidden beneath the board or on the chasis end of the connectors ?

I do not have the answers.
I have the cd104 and cd7550 look the same but the cd7550 sounds better.
I thought someone here had discovered why

Did you put the SAA 7000 in the 14 bit output mode by
putting pin 16 high ?

original in the 104 ( 304) the saa 7000 outputs in 16 bit mode.

You have to put the SAA7000 in 14 bit mode by disconnect pin 16 from ground and connect it to + 5 volt through a resistor of 1k
(FI to pin 18 = +5v)

The removed SAA 7020 takes 16 bit but outputs 14 bit and the TDA 1540p takes only 14 bit !!

Succes

Onno

Hallo,

Thanks.
