Many phonographs manufactured outside the United States used mechanisms based upon licenses received from United States manufacturers. installations where the radio gear was located behind the pilot and only designed for 600 ohm Z earphones and up to 20 pairs could be connected late-1945 and through 1946. receivers incorporated the same improved cabinet as the later RAO-7 and actually offered a couple of 1947 model entertainment radios that shunt to scale the meter to 5x I.) wanted the RBL-3 back again and had to purchase it back from the "output limiter" to cope with atmospheric noise, static, lightning incorporated into the receivers as they were built on the production antenna.
