1650E (70 Hz. to 30 Khz. +/- 1 db max. - ref. 1 Khz.)
Designed for push-pull tube output circuits.
Enclosed (shielded), 4 slot, above chassis Type "X" mounting.
Frequency response 30 Hz. to 30 Khz. at full rated power (+/- 1 db max. - ref. 1 Khz) minimum. Except the
Insulated flexible leads 8" min.
Due to the unique interleaving of the windings BOTH secondary windings must be engaged to meet
Negative feedback circuits can be utilized by connecting to the Green & Black wires - 4 Ohm secondary (this
All units include 40% screen taps for Ultra-Linear operation (if desired).
Typical applications - Push-Pull: triode, Ultra-Linear pentode, and tetrode connected audio output.
For our NEW improved "easy hook-up" secondary series - see our 1608-1650 "A" series.
For the "ultimate" in Push-Pull output see our line of epoxy potted output transformers (1650 potted series).
