My only bad feeling is that the picture is too good, too glamorous. Photo-shopped perhaps??
What are you hinting at? The guy said he received these... as far as we know he's not selling it, right?
Looks real, only i've never seen a 1992 batch...
If its in your player and works, its probably real

As far as i know the double crown S1 is Dutch made, the double crown S2 is Taiwanese made...
I have both:
Philips TDA1541 S1 double crown:
Philips TDA1541 S2 double crown:

All silicom was produced here in Holland, in Nijmegen. The assembly of the TDA1541's took place in Taiwan, India, Nijmegen etc. The assembly took most hours of labour of producing the TDA1541

All silicon was done in nijmegen indeed. As far as i know, assembly/test was done first in nijmegen, later in kaohsiung, taiwan. The print on the chip hence relates only to where the assembly/test/qc was done.
None of the above
Edit: left picture looks a strange crown and s1 print. Still i would vote for real
Edit again: left is fake s1... It's a real tda, but not crown

Hello everybody,
I usually don't hang around on public forums, but this thread caught my attention and I thought I'll stir a pot a little bit.
I've been modifying Philips chipset based players from the early 90's, long before it was in everyone's mouth and long before the internet boom (well, there was Compuserve back then). 🙂
Anyway, there have been a lot of speculation recently regarding unseen date codes, so I went and inspected what I have. Here are some pictures that might help some of you to identify what's what. All of my 1541 purchases were from Marantz service in Germany, except one batch of S2, which were bought from some Hi-End dealer in Hong Kong or Taiwan - I can't remember anymore.
First picture shows TDA1542S1 and SAA7220P/B from the last batch, remains of which is in the second picture. Note the HBH code! I think this should end the speculation about this particular code.
Check the original part number on the plastic bag that came from Marantz (third picture).
Fourth picture shows four 1541's that left from one batch that I bought from Marantz around ca' 1994-1995.
Fifth picture - original Philips "Selection Q" IC's from various Marantz 85/Philips 880 that were exchanged for S2 versions.
Sixt picture - S2 version from that Asian dealer mentioned above.
Seventh picture shows different S2 that was rescued from damaged Naim CD player. Previous owner glued heatsink to it, so when I removed it, parts of the print remained on heatsink. (You can rotate and mirror that image in Photoshop or similar to read the numbers).
Last picture is not that important - it only shows SAA7220's (also purchased in Germany), but, in case someone is worried about the fake ones, here it is, just FYI. Enjoy!
I hope I was able to help somehow.
