What CDP/DAC's used the TDA1541 ?
Since they are hard to find maybe some of those old faulty or for spares (or in the bin) might have some of these.

IIRC the Meridian 206, Arcam Alpha 5 and Naim CD3.

Any other ideas people.

More recently, the Marantz CD7.
It used the double-crown version.
I'm not shure, but I think the Arcam Alpha5/5+ had the TDA1547 (bitstream).

Here you are:

Philips CD160,CD360,CD460,CD650,CD960,CD371,CD373,CD471,CD 472,CD473,
CD207,CD782 (possibly branded 'Magnavox' in USA?)

Marantz CD56,CD65,CD40,CD50,CD60,CD80

Rotel RCD820

Sony CDP-750 (Believe it or not! although the 4x O/S circuit is different from the Philips setup)

Cambridge Audio CD3 (No less than 4 TDA1541's in this one!)

Proton AC300 II (This is a new one on me...I was lucky to pick one up this weekend at a carboot, full working order for 10 (US$15)...nice build and ripe for tweaking)

Many thanks for that. Searched all over here, but forgot AA :rolleyes:

And the Philips CD-880.

Some of these players have killer transports (CD-880, CD-960, Marantz CD-80 etc.). I wouldn't rip the chip out of them!!! Install new and good caps, new clock, some mechanical mods and a brand new output stage and you'll be fine...
(and the non-os mod of course ;-)

what are you planning
what have you on the board?
i have been doing the same as you in the 1541 hunt..:)
had any luck? i have drawn a blank.

robbie 31st March 2003 02:22 PM

what about the laser and its possible replacement?
i have thought much the same and have looked at older naims with this in mine.

Good point. I forgot about that. The lasers are quite old and will need replacement within a few years (or months). Replacements are HARD to find. If anyone knows I replacement for my CDM-1 of the Philips CD-960 !? You could buy two players or rip out the dac and add a CS8412 receiver when the CD-P dies...

The nice thing about an one-box playing solution is that you can feed the clock directly to the dac chip. So no crappy SP/DIF used...

And make a better supply with schottky's/fast recovery diodes. Maybe even an extra toroid, good quality bypass caps etc...

sorry about the miss spelling of your name..
i have had a look at this ,i have a meridan pro which i have thought about playing with,but merdian have said there are no more lasers so that came to an end ( didnt want to damage laser while playing and mess up the whole thing)
have you had any experiments with modding players?
i have scott nixons dac which i like alot,and am looking a gudio tents dac ,the idea being to fit them both into one unit.
