  • Notes

  • The preamplifier is remotely connected to the power amplifier with a cable.

    With the RC/PA pre-amplifier and the best complementary equipment, the TL/12 power amplifier gives the music lover a quality of reproduction unsurpassed by any equipment at any price. It is designed in a form so that the power amplifier can be housed in the base of a cabinet and the small pre-amplifier mounted in a position best suited to the user.

    An original feedback tone control becomes a standard.
    No resonant circuits were employed.

    • Distortion: Less than 0. 05%.
    • Switching for Pickup, Microphone, and Radio, with automatic alteration of tone-control characteristics.
    • High sensitivities. Will operate from any moving coil, moving iron, or crystal Pickup; from any moving-coil microphone; from any radio unit.
    • Controls: Input Selector; Bass Gain and Loss; Treble Gain and Loss; Volume.
    • Output Impedance: 0-30,000 Ω at 20 kHz.

    The unit will mount on the motor-board through a cut-out of 10⅛” by  3⅛”, or it can be bolted to the power amplifier, when, with a top cover, the whole assembly becomes portable.
