• The AMRAD 3500 RF Receiver differed from the 3500-1 by the lack of a plug in RF transformer. The 3500-1 featured a plug in Radiformer that allowed the reception of lower wavelengths. The AMRAD 3500 had a fixed RF Transformer inside of the 3475 tuner. See the model page for the 3475 Broadcast Tuner for pictures of both chassis.
