|LOWER FREQ||HIGHER FREQ|
NOTE: SOME OF THESE WILL BE SECOND and THIRD OVERTONE CRYSTALS AS REQUIRED BY MOST RADIO EQUIPMENT SUCH AS MILITARY, E.F. Johnson, Heathkit, Knight, Hallicrafters radios etc.
CRYSTALS AT THIS VERY HIGH FREQUENCY RANGE are not all guaranteed to be perfectly accurate due to the multiplication factor on the error.
FT243 crystals have pins spaced 1/2 inch apart, and are used in MANY ham radios
the 1940s through 1970s. They are also used in countless military sets such as the BC-611 and GRC-109 etc.
Note- some of these are original FT243 crystals, some are reworked surplus units with
wire lead crystals inside as described in tube transmitter articles using them in CQ Magazine
and detailed technical analysis in Electric Radio Magazine.

These cases hold 120 standard FT243 crystals, as used in WW2 era military radios
and the same crystals have been used in ham radio equipment throughout
the past 50-60 years.
It's a nice green, double-locking case with two compartments that each hold 60 crystals.
Ideal for storing your radio crystals and keeping them from getting lost when you are
not on the air, or they also make a great collectible item.
I currently have one of these left for sale. They go for around $45 to $100 each on eBay.
This is available for $35.00 - for a nice, complete one.
Will sell for $35.00 plus $10.00 for USA shipping.
Some of the FT243 crystals above are remanufactured crystals using original
WW2 era FT243 holders with a newly manufactured, HC49 or HC49US hermetically-sealed crystal
mounted inside. Like all crystals, these should not be used with a grid current
of greater than about 60 mA. They have been used successfully in many typical rigs
like the Heath DX40, HW16, DX100, Ameco AC-1, Drake 2NT, Hallicrafters HT-40, BC610,
Globe King, Homebrew MOPA rigs etc.
Shipping costs will be added to all prices!
