I've emailed AKG about this. The mic is a new acquire. It looks different from my older 480's. Just suspicious. "AKG" is labeled on the board.
I know AKG has gone through some changes in location. Doesn't seem reasonable that some manufacturer would go to this trouble to make a fake.
Thanks,
Dave

Here are some photos of an older 480.

I'm not sure about the newer one, but my 20 year old 480s look slightly different from your old one.
Next, everyone will be asking for comparison audio samples!
-
dlh - I ain't no AKG expert- but:
the old ones in your 2nd post seem to have old style capacitors on the output stage while the "new" ones in post 2 seem to have different or more modern capacitors.
Someone else should know this for sure.

Thanks. Yes I noticed that. Never seen caps like that.

OK, I had some time so had to search more:
from this link: https://www.bornika.ir/Upload/ArticlePhoto/Typesofcapacitor_Photo_20151129133340.jpg
we can learn the "older" capacitors are pcb mount electrolytics, while the "newer" ones are surface mount electrolytics.
So each are electrolytics; from what I recall back in the EE days- electrolytics are "better" for what we do than ceramics or polystyrene. metalized "film" capacitors may have different characteristics which may or may not be "better" for audio use.
I also found these two threads if you are interested:

Thanks for all the digging. Both threads are new to me.

Better living (recording) through science! :headphones:

As pointed out, the most noticeable change is that the two large electrolytic through-hole mounted capacitors have been replaced by surface mount equivalents. This is pretty common in all electronics as through-hole mounted components have been going the way of the dinosaur for many years now.
In terms of sonic differences, I wouldn't lose even a moment of sleep over it. Those are 50v capacitors and used as power supply filters for the 48v phantom; the audio signal does not pass through them.

Thanks. That's exactly the info I needed. Not worrying about it anymore.
