    Those resistors "on top of the tubes" are not just resistors. They are "parasitic suppressors", meaning that they each have a length of bare wire, probably 20 or 18 gauge, wrapped in a coil AROUND...

    Try using an automobile battery (around 12 - 13 volts) to see if the radio faults. It might even be a good idea to have the vehicle running to keep the battery from discharging too much.

    And these reports are made by humans, who don't all have the same degree of hearing acuity or, as in my case, hearing loss. Many older receivers (say from around 1960 and earlier) don't have...

    Hinges absolutely can't be relied on to provide good electrical contact. Sliding contact basically equates to NO contact.

    THAT makes a difference! :)
    I've never experimented on anything above 440 MHz. I'd take a look at commercial antennas, see how they do it and try to copy it.
