    Description

    NOS PAIR THORDARSON T-6755 OUTPUT TRANSFORMERS 100W P-P 800 TUBES W/ WOOD BOXES
    The 6755 transformer is designed for Push Pull Class B use with type 800 tubes. Primary 12,500 ohms CT. Secondary 500 ohms. Designed for type 800 tubes with 1000 V plate voltage. Up to 150ma. Frequency Response rated 30 - 10,000 cps.
    (in testing I found the high end to go much, much higher, ymmv)
    500 ohm secondary for doing distributed audio with multiple speakers. Each speaker using a T-6048 transformer to couple to the 500 ohm line. See pictures for schematics and design notes.
    Could also be used with RK30 or maybe TZ20 tubes. Or any other tube pair that needs a 12,500 ohm plate to plate primary impedance up to 150ma.
    Condition: NOS. Unused in the original wood boxes with paper and "hay" packing from the 1930's. Tested OK for DCR, inductance and voltage ratio. They appear to me to be up to spec. They also look like they were hand made by 2 different craftsman. Your mileage may vary.
    These are over 80 years old. No warranty. All sales are final.
    Sold as is.
    No Returns.
