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.

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 power oscillators, and MOPA rigs etc.
Shipping costs will be added to all prices!
