I'm trying to repair an old radio receiver, it has a missing IC, from
the
schematic this should be a TBA 450, but I haven't been able to find any
data on this IC. Does anyone have a datasheet or at least a pinout of
this
IC?

It's not much, and it's in Polish ...
http://datasheets.pl/T/TBA/TBA450.pdf

That said, it doesn't look like this IC belongs in a radio.

indeed, looks like a TV IC.


OTOH, my vrt databook refers to the TBA450(N)(Q) as a stereo decoder
in a 16-pin DIP/QIP package. Perhaps Philips and Siemens used the same
number for different ICs???

it is definitely what's missing in the receiver.

I guess it doesn't even have an equivalent.
Thanks

Telefunken also used TBA...
