Tests of Neon Lamps as Substitute for Vacuum Tubes in Radio Receiver Output Limiting Devices

Abstract

The tests described in this report were made on a Model RAA-1 receiver. As this investigation concerned only the audio-frequency system, the test signal of 1000 cycles from the General Radio beat frequency oscillator was inserted into the primary of the first audio frequency transformer. Normal automatic volume control curves were made using the 38027 tubes furnished in the receiver for comparison purposes. These curves would be typical also of the early Model RAB receivers. Four types of neon lamps were tested in the 38027 sockets through the medium of adapters.
