I've owned a Phillips CD104B for a while. I'm pretty happy with
the 104 - especially the feel of this solid machine, the sound may
be just a little bass light and the top end a litte harsh, but I
can't justify replacing it yet.
I've already replaced the flying lead with Van den Hul cable, the
bass firmed up a little and I think clarity was improved. I say
"I think" as the lead is soldered at one end, so comparsions are
difficult.
I seem to remember hearing about replacing some capacitors for a
better type can reduce the harshness that can sometimes be present.
Does anyone know about these mods?

I think the mods you talk about are the ones that Marantz do to their
otherwise basic Philips CD players. (Philips own Marantz)
From memory these mods include oxygen-free capactors in the output circuitry
and new power supplies.
The audio benefits can be heard in comparing any recent Marantz machine
(CD45 CD65 CD75 CD96) with the equivalent Philips machine (CD450 CD650 CD750
CD960).
As to where you can buy such capacitors I haven't a clue, in fact I am
looking for similar components (see note 34) but you need to be a dab hand at
soldering to even think about trying.

| 28.2 | mains phase | LARVAE::IVES_J | Fri Jun 16 1989 13:58 | 23 | |
I don't know about those,but one thing I found that reduced the
treble harshness was reversing the mains phase. Since this player
has a captive mains lead you have to do this at the plug end. It
sounds crazy , but if you consider that :-
1) I first read about this in "The Gramaphone", hardly known for
being outrageous.
2) Having done this I found that I could do without the CD attenuater
I was using to soften the sound.
Though it sounds dangerous , I guess the first thing that happens
is that the AC is dropped down through a transformaer and then
rectified ( so why does it work ?). Also bare in mind that almost
all players now have a non-captive mains lead via a telefunken
type plug. This can be inserted either way, and no indication is
given of which way is correct. It's worth a go as it takes only
a few minutes.
I agree the CD104 was one of the best built players yet.
Covent Garden records will upgrade them,using better components,
by the way!
