    Description

    United Transfomer Company (UTC)  Type S-77,  115VAC to 21.5VAC or 17VAC  Transformer.
    Used, seems to work fine.   Can ship USPS Med Flat  Rate, or UPS Ground.
    This is a hefty, well-built transformer.. weighs almost 6 lbs.  Case says "1500V HIPOT", so was factory checked to that level I would guess..
    I ohmed it out, & seemed to get reasonable values.  Also hooked up line voltage to it (pins 1-3), got about 21VAC (no-load) out of each secondary as measured with my old Fluke 77.
    Thanks for looking!!
