Use Of Choke Coil And Transformers In Audio Amplifiers
The article explains transformer and choke coil coupling in three stage resistance coupled amplifiers. It notes output gains of about thousandfold, discusses coupling resistor R and capacitor C roles, grid leaks, and the advantages of transformer coupling including high amplification and simpler operation, while noting distortion and frequency response issues.
Great Britain and America at radio receiving methods duel
American amateurs push ahead with regeneration and amplification and use of choke coils and transformers in cascade amplifiers to maximize per-tube gain and tune outcomes. British radio hobbyists focus on radio-frequency amplification with tuned coupling between tubes under strict government rules. Armstrong leads with the super regenerative system, suggesting the American edge in current progress.
