Is this a real TDA1541A?

I picked up 2 of them. Arrived in about 4 weeks. Then this posting came around and I decided to get a couple more just in case. It took about the same time, maybe a little less, closer to 3 weeks. I am in California.

I'd buy from them again.
 
From our friends on aliexpress...

The one in the first photo is laughable. The second photo shows a better attempt, but still no cigar.

Sometimes the original TDA1541A S1 has been changed by the previous owner !!

Sometimes, Philips fitted a non-S1 TDA1541A.

Don't forget that the S1 were 'hand selected' and marked. Some may be tested as S1 but not marked.
