Re: Tda1541a/s1

This is the genuine Philips TDA1541A/S1 of mine.

Watch for the left white line... That is another difference I can tell..

apassgear: Does your TDA1541A/S1 has this white line? Since we all interesting in building TDA1541's DAC we'd better to have the ability to identify them from fake one.

Any one who knows the whole tale???

This is the S1 in my Arcam Delta 70.2. Looks just like the one you think is fake - no white line - and with the same date code. Same date code as Scott Nixon's - no white line - but the crown is different.

If someone wanted to fake the S1 and the crown - then they would also fake the white line - if that is the real tell tale sign.

Hate to bump a thread from the dead but...

This is the chip in my unmodified CD80:

An externally hosted image should be here but it was not working when we last tested it.

It doesn't look like anything I have seen posted in this thread but I'm 99.99999% certain it is original and genuine!

I can't seem to edit my own threads so here it is again:

[moderator edit] You can now

 

[redpepper]

I come back on which TDA1541 you find on Philips CD880 on my I get a standard TDA1541A (see low right corner of the picture). I buy the player new and it never was on service is completly original except for the output opamp.

Derek,

I'm from Hong Kong too, any chance that you would consider to sell one S2 to me?

Cheers, Raymond

For reference:

I have 2 original Philips CD880's.

1) Unit #1 dated June 1988 - has the TDA1541AS1 crown dac.
2) Unit #2 undated - has the TDA1541A dac.

I believe unit #2 is earlier. It has some seemingly in-house ground wires soldered here and there that unit #1 doesn't have.

Whatever that socketed chip is, it's marked P 203 on the #2 unit and P 204 on the #1 unit.

Both have the CDM-1 MKII transport.

I started a separate thread on CD 880's DAC but now it's clear that these machines have both A and A S1 depending apparently on the date of issue.
Loomis, is there any difference in sound between your players, does the one with S1 sound better?

SONY DAS-R1

Here's a internal shot of a SONY DAS-R1 DAC with 2 TDA1541A S1 double crowns!!!

And here's a close up.

 

[jazzigor]

This seems to be the best SONY combo matching a propriatary transport and the top-notch Philips chip. I read a lot about about this monster which I guess can be obtained in Moscow. It costs a fortune though. I wonder about the sound. Judging by a similarly built Sony 227 ESD that I have, the marridge between a Sony and a Philips (2 TDA 1541A) is not always made in a sonic heaven. But then again, the comparison may not be correct.
