## P.04 - Editorial Notes

PERSONAL
The Grand Final of the Amplifier Championship was a great success. We had a night of splendid reproduction, which will long be remembered by the one hundred and fourteen enthusiasts who were present. It is also unlikely to be forgotten by the ten competitors and their assistants who carried the heavy amplifiers up the stairs to the second floor. The whole contest was a wonderful success in every way, notwithstanding the number of entrants who were unable to compete on account of German Measles. A number of entrants, also, had to withdraw as they had "joined up". Let us hope that by the time the Amplifier Championship for 1941 is being held we will all be able to give the contest undivided attention. In the meantime, however, everything possible has to be done to assist the National Effort. The big problem is to keep the production up to standard and yet comply with the Regulations governing the amount of paper which can be used. Incidentally, a number of readers have written to suggest that we should use cheaper paper, and more of it. As it happens, the Regulations do not deal with the quality of paper used, and even if we used the cheapest paper procurable we would still have to limit the number of papers to our present standard. Fortunately, the scheme for cutting down the amount of paper in each issue, by column rules and narrow margins, has been a great success. Without exception, reports indicate that readers prefer the new size and layout. Apparently the remarks I made last month were far too pessimistic. The paper regulations take into account increases in circulation, which is most fortunate, as we have enjoyed a vast demand in the past three months. Stories get around that the shortage of issues has been due to paper shortage, but this is not strictly the truth. Every month for several months past we have increased the actual number printed, but we have not been able to accurately judge the demand. For this issue, however, we have made quite sure by putting through a record number of copies and there should be ample to fill the demand. A. G. HULL.
