We had hardly finished publishing an amplifier circuit "to end all amplifier circuits" when along came the cathode-follower scare. To add to the confusion, then came the results of the Victorian Amplifier Championship, indicating that beam power valves, even with inverse feedback, do not give the practical results which can be calculated for them by theory. Even direct-coupled enthusiasts were disappointed. In fact, it might be said that the Victorian contest puts us all back about fifteen years in our theories. To cap it all, along comes the latest issue of the famous Wireless World from London, with an article by well-known quality exponent H. A. Hartley, who now confesses that high fidelity reproduction is not desirable. The article is so complete in its coverage and so full of interest in every way that we feel bound to reprint it for the benefit of our many readers who are unable to obtain a copy of the English publication. At the same time we feel that some sort of explanation is needed to clarify our policy in these matters. Some letters have been received from irate readers who claim that we seem to be deliberately misleading them by publishing contradictory stories in quick succession. Briefly, our policy at the moment is to present all these theories as they come to hand. We leave it to you to use your own discrimination as to what you decide to follow.
