A special purpose vacuum tube radio receiver, built to last. Even so, it’s due to have the passives and wiring replaced before its next use.
Whilemost of it is vacuum tube based, it has a single custom-printed PCB with a few
transistors and a single integrated circuit on board. All of the tubes are encased in protective metal shells with springs to prevent the tubes from inching out of their sockets.
The 1302A is from the
1960s, and it is designed to be hooked into a unit with a special
oscilloscope (also rack mounted). I’m told that the combined units intended purpose was to monitor telemetry
data from Soviet ICBM tests and other Soviet rocket
launches! And now it’s mine! How I got it is stranger than most items in my collection.
friends watched a construction worker toss this heavy thing into a dumpster our
freshman year of college. After the worker left, my friends climbed in and retrieved it, and brought
it over to one guy’s dorm room. They tried figuring out what it was before giving up and calling me in. I came over
a half hour later with my toolbox in one hand and pack of oreos in the other. Seems that even after being thrown a good distance, all of the tubes were still intact. I figured out that it was a radio receiver, so I hooked up a makeshift antenna and hit the power switch.
actually turned on just fine, and let us tune in the campus radio
station! My friend gave it to me as a present at the end of that
semester. I found a reason to turn it on every so often, and scanned through its extended tuning range above the normal broadcast FM band. I’ve found some stuff that completely
puzzles me as to its purpose and origin.
