Good day!
Would like to ask if you can help me.
I am looking for all information regarding old Philips DAC Series:
TDA1544;
TDA1543;
TDA1545;
TDA1387.
I'm interested in all kinds of technical information, technology, history, technological differences compared to TDA1541.
Maybe you know the sources where you can get such information.
Thanks in advance!
