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.

From Project Gutenberg

Where either a radio frequency transformer, that is one without the iron core, or an audio frequency transformer, that is one with the iron core, is used to couple the amplifier tube circuits together better results are obtained than where a high resistance grid leak is used, but the amplifying tubes have to be more carefully shielded from each other or they will react and set up a howling noise in the head phones.

From Project Gutenberg

The vacuum tube amplifier and the grid leak are the only new pieces of apparatus you need and not described before.

From Project Gutenberg

The Fixed Resistance Unit, or Grid Leak.—Grid leaks are made in different ways but all of them have an enormously high resistance.
