> I have one, in excellent shape, and was wondering where it was used.  I is very well made, modular, with three plug in circuit boards (RF, IF, det/AVC/audio) 11 transistors, including a push-pull output of perhaps a watt or so.  It has an automobile style slug tuning rack with 4 presets, built with great precision, and has odometer type frequency display.
> It is standard Dzus width, about 2 1/4” tall, and 5” deep.  It has no interface other than 28VDC, lighting, and audio out, with a BNC antenna input.  No BFO or RF gain, so it appears to be AM only, perhaps just for entertainment.  Was this maybe for a VIP aircraft?  Certainly no expense was spared.  Also, no R-xxx number, just AN/ARR-47 on the data plate.  Manufactured 11/58.  Any info would be appreciated.
