Is this a real TDA1541A?

[Malefoda]

What's the "normal" scale of price for each grade?

This is a real thing ! TDA1541A S1

[gabdx]

i remember my tda1540 (real one) overloads the -5 or 5 v supply if i remember... it still works very well and is cool.

Hi

I am a newby in TDA 1541 stuff.

I have a player with TDA 1541A.

What is the difference between this and the single and double crown?

In the attached pic: left = fake, middle = not sure, right = original

The most remarkable at that fake: Pin 1 to 14 = 5K Ohm, Pin 16 to 27 = 3,5K Ohm


As i see in the right a S1 from week 44 in year 88 with Batch 11126
is it possible to have a S1 from later week 10 in year 89 with smaller Batch 11110 in the middle?
I would be grateful for further information to the middle DACs.

Yes,
Look at the font at the top marking of
"fake"
number "4" and letter "A"
if You see these chrs from the same font as marking,
be sure that chip is a fake.
.
I heard that some fake TDA1541A are remarked
TDA1540 chips inside?
but I have not share personal experience about...
cheers

Your "Fake" is identical to that shown by ANDYPAIRO in post#170.

That came from a well-known scammer, 'Tzeng-Albert".

Where did yours come from ?

Yes, this is a fake in the left in my former attached pic as you shown first in your post 137 and andypairo in his post 170.

If i understand right, the font is not the most remarkable. Look at the chips with productionplace JSS. Those seems to be original and have the same different font.

Maybe more the datecode is an indication for a fake. But in a very dangerous kind the possibility to kill your CDP it is.

Someone send me an MKII to modify and he give this chip with. I have mailed him to ask for the source of this TDA and waiting for answer.


Does somebody know somewhat to middle dacs in my pic?

Here, here and here they have the same inscription however deviating ink in S1 and crown.

[poynton]

I don't know.....

The only thing I will say is that the grading stamp, whether for S1/S2/crown/R1 , is always stamped after the main markings.

However, take a look at paul_peraic / post#152 ...
The grading stamp looks as if it was printed at the same time as the main body print and I would say this is a fake.
