Radio Amplifier Hook-Up For Self Contained Sets
Campbell explains a wiring approach for detector and amplifier circuits enabling a self contained unit. The design uses five binding posts, a CO battery, and switch taps to regulate coupling and avoid shorting. This enables experimentation with tuners while ensuring most wiring remains fixed across circuit variants.

Use of amplifiers in radio receiving sets explained
A historical piece explains when and why amplifiers are added to radio receiving sets. It describes regeneration as a common method, with tube circuits and coupling between grid and plate to boost energy before the detector. Long and short wave practices and inductive or capacitive couplings are noted for achieving better signal strength.

Amplification Stages Limit Noise in Radio Tubes
Frequencies of short wavelengths will not transfer tube noises or disturb noises limited to audible frequencies. Several stages may be connected in cascade to amplify the signal strength without distortion before it reaches the detector. Audio amplification may then be added as desired to obtain whatever volume of sound is found necessary.
Grounding the Filament for Smoother Radio Tubes
An old hardware tip explains grounding the filament by connecting a wire from a filament lead to a earth ground such as a cold water pipe or radiator. Grounding reduces body capacity effects, improving detector tube action and stabilizing volume, with a clean contact on a grounded pipe for best results.
