Help - need obsolete chip pinouts

[Mark]

Hi

I'm trying to repair an old Hitachi receiver but I've reached a dead
end without a couple of chip pinouts. These are obsolete chips and I
can't find anything on the net. Can anyone help?

Hitachi HA1196 - Stereo Decoder

Hitachi HA1137 - FM IF amp + AFC

Thanks

Mark

Hitachi HA1196 - Stereo Decoder

Crosses to NTE1484. Couldn't find datasheets for either.

Hitachi HA1137 - FM IF amp + AFC

Crosses to NTE788. I found a datasheet here:
