Mission Impossible, Season 4, Episode 10, "The Double Circle". In the final minutes of the impossible mission most of the team is safely ensconced in an apartment one floor below where Barney is cracking a safe (yes, that's Leonard Nimoy in the background!). The safe is booby-trapped to explode if he makes a mistake in the unlocking sequence. For some reason, they require this SW receiver to listen to his upstairs transmissions from a way-fake-looking handheld transceiver. Once again, Barney is on his own!
Now, who amongst you can identify the "communications receiver" in the photos above? These are the only two shots of the rig in the entire episode. The cabinet color looks suspiciously like Heathkit Green, but the front panel doesn't look familiar to me as a Heathkit. I'd think that meter is probably a giveaway. Obviously, that piece of red tape covers the brand (aahh, the days before product placement took over), but maybe the length of it is a clue? Post your guesses in the comments!
