Ever Ready Model 5318

 I don't believe this set, made in early 1939, was designed to be a portable radio because it's pretty heavy and has no means of carrying it, such as a handle. It was probably aimed at customers without a mains supply and to sell more Ever Ready batteries. Anyway, bakelite would not be the ideal material for a portable radio case. Actually Ever Ready did make a portable radio using the same design as this table model. It was the Model 5214 whose details are recorded below. I have one of these sets which you can see here...click the link I need to extract the chassis of this set from its case and either clean or replace the old plexiglass dial cover because its now so cloudy that the dial markings cannot be seen clearly.

 
 Here's the rear view with the cover removed and you can see that Ever Ready not only made batteries and radios but valves as well. Despite the obvious deterioration due to damp the valve metalising still looks to be in perfect condition. Often when metalised valves are kept in damp conditions the covering falls off. The shape of the valves is slightly unusual and the lettering somehow looks foreign. Maybe they were made elsewhere in Europe?

 

 The set has a frame aerial wound on a plywood former mounted inside the cabinet and the valve lineup should have been as follows:- Frequency changer DK1, IF amplifier DF1, detector & audio amplifier DAC1 and audio output DL2. All have 1.4 volt filaments.

However, at some time in its life, almost certainly around 1955 the set needed a couple of new valves and, because side contact types were quite rare and probably pretty expensive in the UK, two replacements were fitted. These were a frequency changer type 1A7, also marked "DAR10 and Foreign" and a detector/audio amplifier type DAC32. Because these valves use International Octal bases the valve sockets were changed from side contact to a pair of octal sockets. These are marked "Radiospares", the company now known as RS components, which were supplying components branded as such from 1954. Radio sets were very expensive back in the 1950s so changing a pair of valveholders and adding two new valves was a worthwhile proposition. Nowadays that exercise would be out of the question. I must admit to having heard of a 1A7 valve but not a "DAR10" but after thinking about this for a few minutes the penny dropped... the marking is "DARIO", a trade name of Philips..

What I'd read as a number 10 is in fact letters I and O.

The battery was a 1.5 volt plus 90 volt connected by that 4 wire lead, and because it's not a mains set the loudspeaker is a permanent magnet type.
