  • Mounted Galena - Philmore 7004

    This package and the next three items were found in quantity on a recent trip to Oklahoma. They had been stored in the back of an old and now defunct radio store - circa ~ 1950-1960. The packages are original and we are selling these "as is." These items may be of interest to collectors as well as crytal set builders.

    The Philmore 7004 is a single mounted galena crystal; that is, the galena rock is set in a disc of woods metal. The disc fits in our brass cup holder found on our parts page. It also fits in a cup included in the Philmore 7010 Unmounted Galena Detector; see the next item.

    Unmounted Crystal Detector Philmore 7010

    The Philmore 7010 is an unassembled (unmounted) crystal detector kit. While a bit hard to see in the package, it consists of a handle on a rod, a cat whisker, a ball joint and U-shaped holder for the ball and rod, with screw and nut.

    Loopstick Antenna Calrad

    This item consists of a ferrite rod with two coils wound on top of a tube holding the rod. The inner winding consists of Hi-Q Litz wire and the outer coil consists of a few turns; it connects to your station antenna and ground. The inductance of the loopstick is adjustable, using the screw at the bottom or with a non-metalic screw driver at the top opening. Set to the center, the rod is resonant at 1000 kHz in the medium wave band, i.e. the AM band. This was an extremely popular item in the 1950s.

    The loopstick may be mounted by drilling a 3/8th inch hole in a chassis. Simply press the "pound nut" (screw end of the rod) into the chassis. We tried one with our imfinite impedance detector kit and it worked nicely.

    Crystal Radio Plate

    We also found these 3/4 by 1-3/4 inch nice radio "Plates" in the bottom of one of the boxes of stuff. The plates are 25 mils thick and can be mounted with small brads (nails) on a panel. The lettering is printed in black on the brass surface.
