The Morrow MBR-5 receiver and the companion MB560 transmitter with RAP-250S power supply are rather rare items. They were manufactured by Morrow and sold in 1955-1957. I got these from a seller on eBay. I've alway been attracted to their style and compact construction. Their specifications MBR-5 & MB560 are excellent and a MB560 block diagram and schematics of MBR-5 & MB560 are available. Complete manuals are available on BAMA. Here are some more views of these units.
