HERE IS A REAL 1920'S COLLECTIBLE. A PHILMORE CRYSTAL RADIO SET, COMPLETELY ORIGINAL AND INTACT. I LOOKED IT UP ON THE INTERNET AND COULD NOT FIND AN EXAMPLE OUT OF THE MANY PICTURED. APPARENTLY, PHILMORE ONLY USED THE LARGE WIRE WOUND COIL ON THE VERY EARLY MODELS. THE DETECTOR AND SCHEMATIC DATE IT TO AT LEAST 1925. A VERY VINTAGE HEADPHONE COMES WITH THE RADIO, BUT DOES NOT WORK VERY WELL IN RECEPTION. WITH A PAIR OF BETTER HEADPHONES AND A DIODE ACROSS THE DETECTOR, THE SET PICKED UP RADIO SIGNALS FROM MY 80 METER DIPOLE. USING THE CRYSTAL DETECTOR ONLY, I COULD NOT GET A SIGNAL, BUT I UNDERSTAND THAT THEY ARE VERY SENSITIVE AND I PROBABLY DIDN'T OPERATE IT PROPERLY. THE UNIT WILL WORK BUT SOLD AS IS.
