EDITORIAL

I must have been feeling glum when I wrote last month's editorial. Since then I have been going over the accounts and things aren't quite so black as I expected. It now seems that, there will be no need to increase our price, in spite of increased printing and block costs. Just a little more advertising support and it will be possible to turn out improved issues at our present price. First step in the right direction has been the appointment of Paul Stevens as Technical Editor and my personal representative in Sydney. The fine articles which Mr. Stevens has contributed over the past six years have been widely appreciated and he can be counted on to do even better work in this direction in future. He is also a keen businessman and will soon get things organised so that the issues will be out on their due date. It may take a while to get into top gear, but the first of the improved issues should be the September issue, which will take the form of a special "Data & Handbook Issue" which will contain lots of information you'll want to keep handy, such as colour codes for different brands of coils, specifications of components available on the market at present, and so on. Another bright prospect has been provided by some experimenting which has been going on over the past few weeks. It looks as though I have in hand the logical successor to the old "1933 Standard," the most successful set I ever designed. Further testing is being made to probe every possibility, but so far it has shown nothing but the greatest possibilities. — A. G. HULL.
