The H500 'Super Trans-Oceanic' was introduced in May 1951 at an initial price of $99.95 (equivalent to around $1,050 today). It had a redesigned front face and incorporated many frequency coverage and electronic changes ordered by Zenith founder Eugene McDonald. There were 245,000 H-500s sold. There also was a production run in 1953-54, of 27,218 "militarized" H-500's, designated R-520/URR, ordered by the U.S. government for the Korean conflict. This set added a sixth tube, the 50A1, to eliminate power fluctuations. The Zenith H500 was the last of the trans-oceanics manufactured with only 5 tubes, a 3V4, 1U5, (2) 1U4, and 1L6 (RF, Converter, IF, Detector/AGC/first AF stage and AF output) and a selenium rectifier. Subsequent Trans-Oceanic models were manufactured with 6 tubes. In addition to the Broadcast band, Shortwave coverage is provided in six
ranges (2-4MHz, 4-8MHz, and the 16m, 19m, 25m and 31m bands).
The H500 was manufactured from 1951 to 1953, and the radio has 7 bands selected by pushbuttons to the right of the dial:
A detachable 'Wavemagnet' loop antenna is fitted into the lid of the receiver that operates on the Broadcast band (when detached it can be mounted on a window with suction cups), and a very long telescopic whip (‘WaveRod’) is provided for Shortwave reception – an external antenna/ground can also be attached if needed. When used as a portable, batteries are installed in a compartment located beneath the chassis. One of the nice features of the Transoceanic series is the 'RadiOrgan' switched tone control system – providing adjustments for Treble, Voice, Alto and Bass.
