Editorial
Every now and then a new reader takes me to task for my rough and ready way of sketching out circuit diagrams without paying due attention to indicating suppressor grids, for example. Often enough I leave out the symbol for the heater, and my neglect of such things as iron cores in coils, or using the same condenser symbol for even electrolytics, is becoming almost notorious. I can only plead "guilty" to these crimes, but I would point out to my critics that there are several extenuating circumstances to be considered. I consider that "Australasian Radio World" is not the same as a text book, so there is not so much need to be pedantic. Most of our readers are men with a working knowledge of theory, and most of them are busy, so that they want simple circuits, easy to read at a glance, and with all essential details and values clearly shown but not cluttered up with intricacies. I consider, too, that the placing of capacity and resistance values right at the symbol is far more effective than giving each one a letter and then tabulating values, even if it doesn't look quite so professional. Not that it would make much difference if my style was all wrong, for it is now just as much a part of me as my handwriting and my signature. It would be a most difficult task to change either after all these years. - A. G. HULL.
