Hi all,
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? Any cross-reference? Thanks in advance

It's not much, and it's in Polish ...
That said, it doesn't look like this IC belongs in a radio.
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???
FWIW, there are some possible hits here:
In fact there is a TBA450 stereo decoder in the circuit diagram at the bottom left corner of page 3:
- Franc Zabkar
I got one hit at

It's probably a mistake (swapped digits). The IC looks like the reference oscillator for PAL decoders TBA540.
indeed, looks like a TV IC.
it is definitely what's missing in the receiver.
I guess it doesn't even have an equivalent. Thanks

Telefunken also used TBA...
