hi deskmate88,
This is my New user name.
tube-lover.
I change the user name because I had experience of similar design with one of the diyaudio.com memeber. After discuss
to the moderator, he close all the thread but I need to amend of my kits modification for all the 18 buyers in this .com.
so I open another name from siu sin man tho to this tube-lover.
But later may be will change back to siu sin man tho because the moderator after checked & email to me that will open back my siu sin man tho accounr.
pls see the photos of my kits.
I also had large stock of TDA1541a from philips already because I need to match for my kit use.
I had total 500 pcs on hand otherwise I cannot match them.
I was dealer of tango, tamura, james,Hashimoto, Daburu Japan tube output transformer's dealer.
Parts was Elna, blackgate,RMA Sanyo OS-con, Nichicom gold tune dealer.
All my kits use this type of parts.

I can't tell even if I saw the picture, but I think there are people here that can if you post one.
Hi Boban
Try a search on this forum.
If I recall correctly there were a few thread discussing your question... with lots of pictures.

, look at printing, Arial maybe 
That sure looks like a newly printed one 😉 Sorry, but I don't trust that one for a penny.
Nevertheless I hope someone can confirm it is a real A for you. I don't have the absolute truth in detecting fake TDA1541A chips but the font type is new to me as is the series ( and date ).
But if it sounds OK there isn't a real problem, is there ?

Still not try this chip. The year is 1997, latest production. Maybe the S chip remarked 😀

I searched forum before posting, but can't find any pics of the chip with similar label on:
J9927
JSS9721 2
Everywhere is HSH, RSH and similar labels.

OK, but as that is a thread dealing with exactly the same topic, it would have been better to post there, rather than open a new thread. To make things easier for future searches, I am going to merge the two threads together, and in a while, remove these off topic comments
