When I compared the two H500 Trans Oceanics from my collection, there is a remarkable difference concerning the power supply:

   

On one set, I find the power selector for 110 V AC-DC, 220 V DC and 220 V AC;

between the power lead and the phones jack, there is a switch labelled "SEE INSTRUCTION BOOK".

On the other Set, I find no such selector;

there is no switch, but there is "INSERT A.C. PLUG HERE FOR BATTERY OPERATION" engraved in the chassis.

The model with the power selector (with the black cabinet (power resistor ?) is the one found in J. Bryant and H. Cones' Book, the other model is the one found in Sam's Photofact (found at BAMA), it has no traces of the switch having been removed, so I consider it two genuine variants.

You may encounter both models when having a look at the images from our members.
Kind regards Martin Boesch

Der Einführungspreis von $ 99,95 stieg bis zur Weihnachtssaison 1951 auf $ 124,25, wo er dann gehalten wurde.

There was in 1953 a 5th edition (Revision D) of H500 with an additional socket for an optional 50A1 voltage regulator tube. In the empty socket was a jumper plug which enables a 1.200 ohm resistor when no 50A1 was used. So with the installed 700 ohm restistor and the additional 1.200 ohm resistor the heater circuit had the same resistance like the standard H500 circuit with 2 * 950 ohm resistors.

It's likely this last H500 edition was a test series for the RR-520 or it were just spare chassis of this which were used in the standard H500 cabinet. But in difference to RR-520 this chassis isn't using tube shields or a shielded RF-head, and it has no dial light.

$ 99.95 was the introductory price which then jumped up to $ 124.25 for Christmas 1951 and later.
