All American SAR- Radios from their beginning to 1968 are part of the collection.
More modern ones are (still) too expensive....

RT-285 / URC 11 (1954)
is an American SAR -Radio, used by the Air Force and the Navy.
It is the first SAR hybrid radio, i.e. it uses transistors and tubes together (see picture gallery).
Tubes were in sockets because they wore out. A tube tester told you when a
tube was worn out.
Transistors replaced tubes. Therefore, they needed to be in sockets, and so
obviously they needed a tester to test transistors..... except that you
didn't really need sockets or a tester because transistors do not generally
wear out. The joke was on the taxpayers.
