grid leak

noun

, Electronics.

1. a high-resistance device that permits excessive charges on the grid to leak off or escape.

This done connect the negative, that is, the zinc pole of the B battery to the positive electrode of the A battery and connect the positive, or carbon pole of the former with one end of the grid leak and connect the other end of this to the plate of the amplifier tube.

To the end of the grid leak connected with the plate of the amplifier tube connect the metal point of your crystal detector, the crystal of the latter with one post of the head phones and the other post of them with the other end of the grid leak and, finally, connect a fixed condenser in parallel with—that is across the ends of the grid leak, all of which is shown in the wiring diagram in Fig.

A Radio Frequency Transformer Amplifying Receiving Set.—Instead of using a grid leak resistance to couple up the amplifier and detector tube circuits you can use a radio frequency transformer, that is, a transformer made like a loose coupled tuning coil, and without an iron core, as shown in the wiring diagram at A in Fig.

From Project Gutenberg

To use the amplified radio frequency oscillating currents or amplified audio frequency alternating currents that are set up by an amplifier tube either a high resistance, called a grid leak, or an amplifying transformer, with or without an iron core, must be connected with the plate circuit of the first amplifier tube and the grid circuit of the next amplifier tube or detector tube, or with the wire point of a crystal detector.
