The Swan 500 was a more costly version of the 350, with higher output power and more operating features. Although they lacked the higher selectivity and tuning accuracy of higher priced transceivers, each performed solidly as a basic SSB station. They both used an outboard AC power supply with a built-in speaker, the model 117C and its variants.

The company was founded in 1943 by radio design engineer Robert L. Drake. The company began as a manufacturer of low pass and high pass filters for the government and amateur radio market, and after World War II, produced amateur radio transmitters and receivers and communications receivers for maritime mobile service.

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
[16] [17] For a comparison, a 500-watt power supply carrying the 80 Plus Bronze efficiency rating (which means that such a power supply is designed to be at least 82% efficient for loads above 100 W) may provide an 84% efficiency for a 100 W load, wasting only 19 W. [18] Other ratings such as 80 Plus Gold, 80 Plus Platinum and 80 Plus Titanium ...

In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
