EDITORIAL

In the April issue of a contemporary magazine are advertisements from various firms offering the Cosmocord pickup at prices of 59/6, 66/-, 67/11 and 75/-. The same item was advertised a few months ago at 77/6. The cartridges for this pickup are advertised in the same magazines at prices of 31/-, 37/6 and 45/-. The "Young Atom" pickup is also advertised at widely varying prices of 57/-, 57/6 and 70/9. A number of our readers, who also read the other magazine in question, have written to me to ask if I can offer any explanation for the terrific difference in prices quoted. Some of them actually purchased pickups at the higher prices prevailing a few months ago; now they feel that they have been robbed. Knowing that my little publication is completely independent, without any trace of trade association or obligation, and that I will give them the honest "low-down" on the position, they have come to me with confidence. I cannot betray that confidence, although it puts me in a tight corner. I feel that the only way to handle the problem is to explain to my readers the whole background of the position. I feel sure that they have sufficient intelligence and logic to be allowed to know about these things. Most of them already know that Father Christmas does not necessarily climb down the chimney. Some even know that babies are not found under cabbage bushes. They are old enough to know about radio trade prices and discounts without being shocked. So the first article of a series covering this subject appears in this issue. — A. G. HULL.
