    Description

    For sale is one
    pair Vintage UTC HA-133 Single Ended Tube (SET) Line Stage / Pre-amplifier Output Transformers as Seen In the Pictures! Pictures are of the actual transformers you will receive!
    All Coils Are Tested with a Signal Generator using sine wave from 20-20KHz and an oscilloscope.
    HA-133 is made of UTC famous HyperMalloy Series Core and offers very flat frequency response from 30Hz to 40KHz within +1 and -1dB according to UTC data.
    Both units are physically and cosmetically in good condition!
    I will include a printout of the UTC Terminal Hookup (Pin out) with them.
    Primary Side has 15K ohm impedance in split coil / winding.
    Secondary Side has 50/125/200/250/333/500/600 ohm impedance in two winding (sections).
    It can accept 8mA maximum DC in the primary connection / winding for direct feeding of Plate to Line output in the Single Ended Tube Circuit design.
    Each transformer weights about 3lbs so total shipping weights is around 8-10lbs.
    I will be listing many UTC and ADC Transformers in the next few days so check out my other items.
    Please NOTE THAT these transformers are SOLD AS-IS.
    Return is NOT Accepted Due to the nature of the Vintage Item.
    I only sell the good parts and want to make sure you get the good parts.
    They will be packed well for safe shipping.
