Radio Do's and Donts for Oscillation in Vintage Circuits
The guide warns that oscillation strength varies with tuning and component ratios and cautions against detuning when adjusting the tickler and grid coils. It advises using a constant L to C ratio, not over-tuning sensitive stages, and suggests testing multiple detectors, favoring a soft gas tube as detector and a hard tube as oscillator. It also cautions against moisture-absorbent coatings on coils.
