Single-Ended Tube Audio Output Circuits

Hammond Manufacturing Single-Ended Tube Audio Output Circuits feature the 1627-1642 Series with 30W output power and 20Hz to 20kHz minimum frequency response at the full rated power. This series is "overdesigned" for high fidelity, single-ended, Class A tube output circuits (triode, tetrode, and pentode tubes). The modules are enclosed (shielded) with four-slot, chassis Type X mounting and have 8" minimum insulated flexible leads. The core is gapped to reduce core saturation in Class A tube amplifier circuits. For versatility, all units except the 1642SE and 1638SEA include a 40% screen tap for ultra-linear, tetrode/pentode operation. The 1642SE and 1638SEA do not offer this screen tap because they are designed primarily for high impedance triode tubes. Hammond Manufacturing Single-Ended Tube Audio Output Circuits operate in a -40°C to +105°C temperature range.
