1627SEA

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1627SEA 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 20 Hz. to 20 Khz. at full rated power (+/- 1 db max., ref. 1 Khz.) 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.
