The "Cabin Set" Eddystone 670A is a AC/DC all wave receiver intended for shipboard use. It was installed in the cabins of first class passengers and ship's officers to listen to radio stations from their homes during the cruise.

Single conversion superhet, I.F. 450 kHz

Analog dial, bandspread dial

AC/DC receiver

The nice looking tabletop radio can be powered from 110, 200 or 230 V mains, it is a AC/DC set so it could be connected to mains outlets on ships with both AC or DC installations.
The receiver's dimensions are 42 x 26,5 X 22 cm.

The upper part of the frontpanel is taken by the dial window, the receiver comes with a large "slide-rule" dial in contrast to the older "Cabin Set" 670 with it's semicircular dial. The broadcast bands are marked in red, the maritime communications bands are not covered, there is a small rotary logging dial and a "magic band" tuning indicator.
The receiver comes with only four controls in the bottom part of the front panel: the tone control is combined with the ON/OFF switch, the band selesctor with the four settings (Band 1: 150-380 kHz / Band 2: 540-1500 kHz / Band 3: 5,8-13 MHz / Band 4: 12,8-30 MHz) and a gramophone input. Note that the maritime communications bands are not covered. At the right, you find the main tuning knob and the volume control.

The Eddystone "Cabin Set" 670A is a neat looking simple shortwave receiver which has been used a shipboard receiver mainly in the cabins of first class passengers, the demand for such sets decreased when transatlantic passengers get used to travel by plane - many of the receivers probably ended on the scrap together with the classic ocean liners.
The Eddystone 670A still can be used to monitor strong international stations on the shortwaves, although it has no CW or SSB reception capabilities, as it is an AC/DC set, I recommend to power it only from an isolation transformer.
