ANTIQUE HAM BAND CRYSTALS - for less than $2.00 each.

Military surplus crystals from the Golden era of radio.
Build or restore
something true to the period of the 1930s and 1940s.
Three batches of
crystals are currently available. See list below.

These large crystals are some of the earliest made for
use with regular
military radio equipment. There is not a lot of
information about
them available any more. Some were used in type SCR-522
radios, BC624,
BC625, ARC3 etc., etc. However, these would make a great
basis for
a homebrew, old-style glowbug AM or CW transmitter since
they are almost
all on useful ham band frequencies. Enough here to share
with a friend
too on some requencies! Will be quite a conversation
piece around the shack.
