NEW-OLD-STOCK HIGH IMPEDANCE MILITARY HEADSETS!!


 

New Old Stock Military Surplus High Quality High Impedance Magnetic Headsets!! Borden Radio Company has acquired a number of these new old stock, totally unused, High Quality 4400 Ohm magnetic headsets. These headsets come with a six foot rubber covered cord and a 1/4" standard phone plug. They perform very well with our Cornell WW-II Foxhole Radio, our Crystal Radios, and with our Armstrong One Tube radio. They work very  well with any crystal or tube radio. The high 4400 Ohm Impedance allows crystal sets to tune sharper by not loading down the tuned circuit as much as regular 2000 Ohm headsets. These fine headsets were made in China from the 1960s to the 1990s for military use in tough battlefield conditions. They are extremely well made and are very rugged and also sensitive. We clean these and thoroughly test each one before it is ready to go out. We guarantee them to perform as advertised.

BOGEN T-725 IMPEDANCE MATCHING TRANSFORMERS!
bogen xfmr

These are the transformers that everybody in the crystal set world is talking about. These high quality transformers were designed by Bogen for PA systems in buildings where multiple speakers are used. A variable impedance matching transformer is needed at each terminal because of the varying number of speakers used in these custom installations. These transformers also just happen to be absolutely perfect for matching various low impedance headsets to the high impedance requirements of crystal sets and one tube sets. When used with one of our 12 position rotary switches and some fahnestock clips, you can build a very versatile variable impedance matching device called the "Uni-Match" as described by Steve Bringhurst on the Impedance Matching Headphones To Radio  link on Darryl Boyd's "Stay Tuned" web site: http://www.crystalradio.net

XICON MINIATURE IMPEDANCE MATCHING TRANSFORMERS!
xicon xfmr


These high quality miniature audio transformers work well for matching low impedance headsets from low impedance to high impedance. They are a very good economical solution to your impedance matching needs. The Primary is center tapped 50K ohm impedance and 1.2 K ohm D.C. resistance. The Secondary is centertapped 1 K ohm impedance and 42 ohms D.C. resistance. They work very well in matching 32 ohm to 600 ohm headsets to crystal sets and one tube sets.

XICON MINIATURE IMPEDANCE MATCHING TRANSFORMER $6.95 each

BRAND NEW CERAMIC EARPHONES WITH TINNED LEADS!!
 

phonenoplug

These are brand new ceramic earphones that are made to an old case design. They are extremely loud and sensitive and will enhance the performance of any crystal set because of their near infinite impedance. Too low an earphone impedance will make a crystal set's tuned circuit tune broadly and with reduced volume. These flesh colored earphones are exact replacements (except for color) for the earphones on the old Rocket Crystal Radios and Miniature Germanium Crystal Radios. The original earphones can be replaced without harming the vintage radio and will bring them back to their original performance. The radios can be easily returned to their original condition when desired. Made in Taiwan.

  $6.95 each
Add a pair of Old Style Pin Plugs for a Total of $8.00 for an earphone and two pin plugs.
