Hello Audio Shockwave:
The loudest radio ever ah, hard to answer that one.
But the General Radiotelephone Super MC-11A where real loud, and there where up graded to the MC12. These radios where made by General Radiotelephone in Burbank California, on Burbank Blvd, near Hollywood Way St.
The MC11, MC11A, and Super MC11A radios used a German Audio Tube that was a driver inverter, and Push Pull function for the finial audio tube. General Radiotelephone upgraded the MC12 to have much larger and powerfull tube as the finial audio tube.
As the FCC
tighten up the specifications on CB
Radios, and required type acceptance, the General Radiotelephone Radios fadded into history.
Many use to call the General Radiotelephone Radios as "Junkey Generals" as the Golden Screw Drivers where placed in the wrong place, and the radios bleed quit a bit. But loud as all get out.
The General Radiotelephone SB-72 was a early AM
Radio. One of the 1960's deam CB
These old General Radiotelephone CB
radios can be seen at: members.aol.com/radiokbob/page5.htm
A truly rare web site and rare radios.
I meet George Maragold in the mid 1960's, (who was the chief designer at General Radiotelephone) as I blew up the ol Mans (Dear ol Dad) Super MC11A CB
Radio, on more than one occasion. Whick cost me years of chores, but was worth it!
