    Vintage 1970's. Covers 80m through 10m. Originally sold in the US by Henry Radio. Yaesu also sold and branded this radio is the FT-200.

    I obtained this radio from my uncle's estate. I've been licensed as W4LKR since 2012. Feel free to contact me with any questions you have. This would be ideal if you are interested in restoring older models as it does need some refurbishing. Photo #5 points out a component that needs replacing. The radio powers on and static is heard through the speaker, but the indicated component has generated some smoke, so I have not tested the unit further with an antenna connected. I believe the burned out component may be a transformer or a choke, but I am not certain.

    Asking $200.00, shipping within continental USA included.

    Please PM me if interested and I'll forward my contact info.

    Thanks for looking.

    THATS A FILTER CHOKE THAT SMOKED, PROBABLY NEEDS NEW DIODES AND CAPS IN THE POWER SUPPLY.

    I'm wondering if that is the transformer for the speaker.

    Don't have a schematic to know if it has a choke in the power supply.

    Could be either in my opinion since a choke or audio/speaker transformer look almost the same, sometimes, and the only way to know is if it has two wires which would mean a choke. Four wires would mean an audio transformer for the speaker. In fact, the one near the back panel may be a choke and the one you indicated would more likely be a speaker transformer since it is nearest the speaker. At this point, I'm guessing...

    I checked out the power supply schematic. There ARE two 2.5 Henry chokes in the A/C power supply.

    Don't forget about the box full of tubes. Not included, but also available :)

    The audio transformer is on the main chassis, the smoked item is indeed a choke.
