Default Upgrade for Philips CD304

Today I was pleasantly surprised when I bought a Philips CD304 for 1 Euro. It sounds as good as my Arcam, so that was a pretty good buy. Of course, the next step would be to improve it.

Are there any suggestions about what I can do to make it sound better?

Judging by this picture I found on eBay it would be a mark II. Or at least the seller claims his is a mark II and mine is similar if silver.

Click the image to open in full size.

It sasy it is a 304/30 on the back. It reacts to the regular Philips remote and features the headphones output with regulator. At this moment I don't have the time to open it up (and besides, it's playing ), but if there is anything else you need to know to know what to do to it, I can provide pictures of the inside probably tomorrow or maybe even tonight.

Ok, then it isn't a Mark II. It has got no digital out and it doesn't say a whole lot on the front...

So what is possible?

This thing is a 14bit machine with 2 x TDA1540 and you can't do anything about it.

But sound is not so bad.

disconnect both the ouput and the headphoneamp from the pcb.
Solder new interconnects to the pcb.
Reclock the clocksignal from saa7030 to TDA1540s,or try the clocksignal from the saa7000.

Or just enjoy the machine as it is.It probably beats any TDA1541 machine hands down.....

Did you search this forum?
Philips CD304 mods

Or use Google?

I own the equivalent Marantz CD-74, better built but more difficult to modify

Good luck!

Perhaps because of the german,but does he seriously imply to use it without cover???
The rf interference will reduce the quality of sound.
