PIEZO HEADSET FOR CRYSTAL AND REGEN RECEIVERS (HIGH IMPEDANCE)

Description

THIS IS A PIEZO HEADSET THAT WILL WORK FOR CRYSTAL AND REGEN RADIOS. THEY ARE HIGH IMPEDANCE AND WILL SERVE AS A REPLACEMENT FOR THE OLD TRADITIONAL INDUCTIVE TYPE HEADPHONES IN THE 2 TO 4K OHM RANGE.
THE HEADPHONES ARE QUITE SENSITIVE AND WORK GREAT WITH MY REGEN RADIO SHOWN IN THE PHOTOS, WHICH HAS A HIGH IMPEDANCE CAPACITANCE COUPLED OUTPUT  (RADIO NOT INCLUDED IN THIS AUCTION).
I'VE ALSO HAD EXCELLENT RESULTS USING THEM IN CIRCUITS WHERE YOU HAVE A TRANSFORMER COUPLED OUTPUT WITH AN IMPEDANCE IN THE 2 TO 10K OHM RANGE (OR HIGHER). OF COURSE, THEY ALSO WORK GREAT FOR CRYSTAL RADIO RECEIVERS.
IN MY PERSONAL EXPERIENCE I HAVE FOUND THAT THE PIEZO ELEMENTS ARE USUALLY MORE SENSITIVE THAN THE OLD STYLE HIGH IMPEDANCE INDUCTIVE HEADSETS THAT HAVE BEEN USED SINCE THE EARLY 20TH CENTURY.
THE PHOTOS ARE GENERIC. I HAVE SEVERAL IN STOCK AND THEY ALL LOOK THE SAME. MADE FROM NEW PARTS THAT I PURCHASED ONLINE.
PLEASE SEE THE PHOTO OF THE PIEZO ELEMENTS THAT ARE INSTALLED (ONE IN EACH SIDE OF THE HEADSET).
