I don't know for sure what your things are, but judging from the labels
stamped into the case, I think they might be TV tuners or modulators or
perhaps a corresponding part for satellite TV. Perhaps they are a
similar part for some other application.


I am assuming, perhaps wrongfully so, that since they were made for Lear Jet,
they are the front end of one of their radio receivers, whether it be for the
aircraft band, or locator/directional beacons possibly. That's just a wild
guess. I wrote to Mitsumi requesting information, but I haven't received a reply
from them. Lear Jet is another possibility, but they have since been taken over
by another company, and as these are older parts, there may not be any
information available any more. I was hoping someone in this group may have come
across them in the past. Thanks anyway..
