Note that I never mentioned China in my original post so you made an assumption which may or may not be valid. Actually as a former employee of two semi-conductor automated test equipment companies I have fairly direct if second hand knowledge from Chinese employees I knew whilst working for those companies. Average salaries in China for a somewhat skilled production worker are on the order of a couple of dollars an hour, good engineers make about 1/3 what they do here in the USA. The statistics on Chinese wages are widely available if you google for them.

I'm sorry if you took offense at my comment about the economics of counterfeit parts, but I have had just a little bit of experience in the matter as a design engineer and it is a big problem even with very inexpensive parts.

I can't speak to whether or not these parts are actually fake or not, not having seen or more importantly tested them.. (Which might include depackaging and comparing die between devices of known and unknown origin.)
It is people such as yourself that takes out the enjoyment of being in such a forum as it has gone from the authenticity of a chip , to the injustice of world affairs and now to your unsurpassed knowledge because of your prior employment , please over come your own persona and just leave it be , if I wished to discuss politics and the injustice of world affairs I would be on some type of NBC news forum , which I suggest you try .

P.S. I think you summed it up yourself with "I can't speak to whether or not these parts are actually fake or not" because then you would know and not assume .

Please note these were laser engraved like modern chips and not stamped. BTW I seriously doubt the story that they were hand stamped in the eighties. AFAIK only the crown symbols were hand stamped.

The beloved TDA1541A is being produced again it seems ... Too bad for Ebay speculants.
How did the 2004 chip sound ?

Nice chatting with you, you've pretty much said it all, have a nice evening. I'm off to the gym now.

Hi

I have 6 old TDA1541A that I was thinking of selling, had them since 2001 to build this project but never got around to it (that was me in the email)

see

source of tda1541a chips - steveor - Tweakers' Asylum

The text is 11121 HSH8918 2 , all have Philips logo

but did I understand that Jean-Paul state that they were now back in production so essentially worthless?

thanks
Steve

Take a look at his feedback.

All 'Private' except for very low priced items (probably genuine sales used to boost his feedback rating).

That fact alone would make me very wary of buying from him - not to mention discrepancies in typefaces etc.
