FOR SALE:

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.
