1630SEA

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1630SEA SINGLE ENDED “CLASSIC” TUBE OUTPUT TRANSFORMER – ULTRA-LINEAR         Over designed" for high fidelity, single ended, Class-A, tube output circuits (triode, tetrode or pentode tubes). Enclosed (shielded), four slot, chassis Type "X" mounting. Frequency response at least 20Hz. to 20Khz. at full rated power (+/- 1db max., ref. 1Khz.) Insulated flexible leads 8" min. For maximum versatility, all units (except the 1642SE & 1638SEA) include a 40% screen tap for Ultra-Linear, tetrode/pentode operation (if desired). The 1642SE & 1638SEA do NOT include this screen tap as they were designed principally for high impedance triode tubes. High quality laminations, (M6) grain oriented silicon steel. Core is gapped to reduce core saturation in Class-A tube amplifier circuits. For general purpose or replacement use in single ended tube output circuits see our 125SE Series.
