Is this a real TDA1541A?

I test the two S1 in the middle of the pic:
1. Separat pin 2 from 4, it still plays musik
2. Separat pin 16 and 17 from extern dem-cap, small distortions in the heights begin

So they must be minimum a TDA1541 with A. They never soldered and the housing show no marks or scratches. It seems that they are new old stock.

I really should check in here more often ! Just ordered one marked as a 98 Taiwan (HSH), we shall see if he's still selling fakes or not. I'll keep you all posted .....

Don't like the S1 and crown. The markings don't look genuine... Got some S1's from HSH 8905 and markings are stamped on and have different shapes.

Where did yours come from ?

I get answer about the source of the faked chip in the left oy my attached pic. It comes from ebay seller tzeng_albert in Hong Kong. After lodge a complaint he pays back the 10 €.

But who would pay the defective CDP if this chip would have been inserted? tzeng_albert knows that his chip is a fake minimum since October 2009.

Hi,

I also recently received the same " "Fake" is identical to that shown by ANDYPAIRO in post#170."

from power seller with 99,7 % good feedback ebayer Tzeng-Albert with number HSH0123. I mailed him about it and he will sent another one with another batch number...

Regards.

Just received the replacement, it 's Taiwan labeled and with curve fonts, looks real but can't test it for the moment but looks the same as post 170 replacement chip. Regards.

So can no one tell me what these are ?

The seller said they were S2 ?

[JonHarrison]

Fakes ?

[paul_peraic]

O.K. fakes but no theoretical history about them ?

[JonHarrison]

Well to the best of my knowledge that last ones were made in 1999/2000. It has been suggested that some of the fakes are relabelled 1540s but in my experience whatever they are they smoke your powersupply! Where did the photo come from ?
