Everready tube portables

Model C Sky Queen Sky Casket

Brand and type: From left to right: Model C from 1946 - Sky Queen from 1952 and the Sky Casket from 1953. Everready is very British. They made a whole range of portable models called King, Princess, Countess, and so on.

Cabinets: The Model C is all acrylic (or a similar plastic). The others are built from plywood covered with snakeskin (Queen) or a marble effect leatherette cloth (Casket). The speaker of this one is in the lid. The Model C is rather tall with its 34 cm.

Tubes: Nothing special, all have 4 pieces of the 7-pin battery tubes.

Power: The C and the Queen both want a combined low/high tension battery of huge proportions, the Everready B136 is a real "power pack". It should be with a mass of 2.5 kg!
I guess the filament part (1.5V) takes 2/3 of the volume. Does anyone know how long these batteries lasted, and their original price?
The Casket is more humble in its needs, it takes the smaller B141 battery. Both types provide either 90 and 1.5 volt.

Nowadays these power sources don't exist anymore (though replicas seem to be built again, to cost you an arm and a leg). So if you want to play your radio in the field: just make your own high-tension battery. Buy 10 pieces of the 9V block battery, tape them together and put them in series. For the filaments, buy a few D-cells and connect them parallel.

Expensive? Yes, as are the replicas. Buying the batteries at this time (4-'98) to build your own, would cost around 100 Dutch guilders ($50), so I only play them at the bench, where I have all kind of power supplies.

It's not the real thing, I know. But who wants to make all kinds of batteries for all his radios? Other radios take a much smaller size and lower voltage, 75V for instance. I could take 3 pieces of 22.5V, but at the photoshop they want a fortune for these things. So they are convicted to play only at home, who cares? The first Bell telephone doesn't work either in a modern network.

Bands: Long and medium waves for all three.

Controls: Again nothing special. Volume-on/off, tuning and a band switch.

Obtained: The Casket came from a blind guy who is now into taperecorders. The others from flee markets around 1985.

Condition: The Casket is the real handsome guy, the other two are only a bit uglier....

Working: Splendid all three. The electrical design is "straight ahead", there are only minor differences between radios using these tubes.
