I dont know how many people will see this or even if it is appropriate for me to ask here since I am new but.....
I have an old short wave radio that belonged to my grandfather and was passed down to me by my father (who was an electronics tech).
The output IC or this HA1329 IC originally made by Panasonic Corp dates all the way back to the 60's however I cannot seem to find one for the life of me. I have contacted Panasonic, Digi-Key, Texas Instruments, Motorola, Sony and just about every parts manufacturer I can possibly think of which leads me to believe that the only place I am going to ever find one of these is in some guys parts cabinet.
So if you run across one of these or a substitution for it please let me know.
