Location is defined by the letters.
To quote the duchaudioclassics website:

1541 code ABC 1234 (Y):
A: silicon processing facility
B: assembly facility
C: test facility

12: year
34: week

Y: development chip (no standard chip m ask was used)

The names of the facilities are:

A
H: Nijmegen Holland
J: Caen France
R: Hsinchu/TSMC Taiwan

B
H: Nijmegen
S: Kaohsiung Taiwan
B: Hamburg Germany

C
Nijmegen Holland

So a TDA1541A HSH9236 was processed in Nijmegen, assembled in Kaohsiung Taiwan, tested in Nijmegen Holland.
It was produced in the year 1992, week 36. A TDA1541A S2 RSH9713 was processed in Hsinchu/TSMC Taiwan, assembled in Koashiung Taiwan, tested in Nijmegen Holland.
It was produced in the year 1997, week 13.

I’m interested in trying a dual mono implementation of the TDA1541A with Ryan’s D3 boards.

I have only one new old stock TDA1541A right now and would be interested in a pair of the Taiwan TDA1541A or something similar.

My only other option is to try and pull some TDA1541A from broken players I have and I’m not sure that will go well.

Please feel free to PM me if you have anything for sale.
