Push-Pull Tube Audio Output Transformers

Hammond Manufacturing Push-Pull Tube Audio Output Transformers are designed for general-purpose use and, depending on the series, replacement use in push-pull tube output circuits. The 125A-125E Series, 125H Series, and 125J Series all feature 150Hz to 15kHz frequency response at full rated power (±1dB max., ref. 1kHz). The 1608-1650 Series, 1608A-1650A Series, and 1650P Series all offer 30Hz to 30kHz minimum frequency response at full rated power (±1dB max., ref. 1kHz). Hammond Manufacturing Push-Pull Tube Audio Output Transformers are RoHS compliant and designed for maximum versatility.
