FT243 Radio Crystals FOR SALE

Our crystals are featured in CQ Magazine October and December 2004 issues
in the "World of Ideas" articles by Editor Dave Ingram, K4TWJ, on a "6L6 Resurrection - 2004 Style."
This is a construction project for a power oscillator transmitter using the venerable 6L6 vacuum tube.

These crystals were also featured in an 8 page technical report in ELECTRIC RADIO
magazine for May 2005 by G3UUR. Materials science expert Dr. David Gordon-Smith, G3UUR conducted
some very tough tests on these crystals using a high-powered Pierce power oscillator circuit
and discovered that some of them could withstand internal temperatures of over 200 degrees Celsius.
In some cases they can actually prove to be MORE reliable than the old World War Two era
FT243 crystals. The crystalline structure is more pure and less prone to failure.

FT-243 crystals have pins spaced 1/2 inch apart, and are used in MANY ham radios made from
the 1940s through 1970s. They are also used in countless military sets such as the BC-611, TRC-77 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.

NOTE:


Most (not all) of our FT243 crystals 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.
