## P.04 - Editorial Notes

PERSONAL
Under the rationing regulations which control the amount of paper we are permitted to use in this production, it appeared most unlikely that we would be able to offer anything in the way of a bumper Christmas issue. Yet we felt that something should be done to produce a special issue which would express the appreciation we feel for the splendid support which readers have given us during the year. Not to be outdone in this resolve we have therefore cut down on this issue to a minimum, getting in as much technical matter as on hand, but squeezing it in to 36 pages. This saving in paper will allow us to carry out the idea of the special Christmas issue, and it should be on sale about a week before the holidays. In this special issue we hope to be able to have at least sixty pages (although we'll have to weigh up on our quota to make sure). In these sixty pages we hope to have some very special articles, including full details of two more championship amplifiers, the rest of the picture diagrams and photos covering the construction of the portable set which is announced in this issue, and also several completely new technical articles. It may seem a little like robbing Peter to pay Paul, but we can only ask your tolerance. Things aren't what they used to be. Which thought brings to mind that if we understand the budget proposals correctly there will be quite an incentive to radio set building, as complete sets carry the 15% sales tax, whilst radio component parts are taxed at only 10%. Why radio sets should be classed as luxuries, and put in the 15% class seems a little hard to understand, as in most homes a radio set is just as much a necessity as the clock on the mantelpiece or the newspaper on the table. However these things come to us, wrapped up in a story of national effort, so that none of us feel any other sentiment than that we have to endure them as best we can. The main thing being to "do your bit" and "carry on." A. G. HULL.
