  • Product Description

    Thick, sweet action. Lots of heavy metal in the box; transformers, tubes...add some weight to your tone!

    "The Gates SA-39B Limiter may be used for all modes of broadcasting, AM, FM or TV nd is designed for very low distortion, wide audio response and as an aid to fine programming.

    Three audio stages stages, all push-pull, employ highly shielded transformers and carefully selected components to assure good balance and low distortion. Limiting action is derived by application of a portion of the output voltage through full wave rectification to the main and second control grids of the first audio stage. As output increases, the grid becomes more negative, lowering the gain of the amplifier.

    To further assure constant performance under varying line voltages, and electronically regulated power supply maintains constant voltage to the first two audio stages.

    The recovery time of the limiter is set by a switch on the rear of the chassis. A dial is calibrated for six positions: Position #1 gives a time recovery of .2 seconds, and each succeeding position increases this by .2 seconds."
