Bang & Olufsen Beomaster 700 Radio
I was raised to repair the B & O Beomaster 700. Monaural radio with three ranges of wave, the year is 1964. Held in poor conditions. Many traces of oxidation inside the corroded fuse carrier, welds deteriorate, the wire line of FM broken. After some time I managed to repair it and return it in good condition and replacing some capacity electrolytic. There is the tune knob non-original and a few screws back on a wooden rather than threaded. In fact, I was somewhat disappointed by how it is constructed, without reference components to the board and some insulation on the mains 220v missing. However, an excellent sound.

Cool radio, looks like you can just get above the AM (MW) band, I see you can also get 1600 to 4000 kc on that band. I know 30 years ago and more, it was called "The Marine Band" since a lot of ships used that band. I have the same band on my Sanyo RP-8700 and 1953 Philco "All American 5 tube" radio. It is good to have so you can receive up to 1700 kc with that newer extension to the AM band plus if you go beyond it, you can get the tropical 120 meter and 90 meters bands. I remember back in the 1980's, I think it was the then editor of "Popular Communications," Tom "Tomcat" Kneitel (RIP, he died recently) that advocated more use of those bands too to clear AM radio congestion and to have longer ranged stations at night.
Getting back to the old Philco, back in the day, many police departments used areas around 1700 kc and 2000 kc for radio dispatch and the 1600 to 1700 kc part was to be used for Civil Defense communications (not CONELRAD) by emergency crews, I have a big "CD" sign on where to tune. I should post a pic.
