3 FT-243 RADIO CRYSTALS FOR THE OLD BOATANCHOR 40M CW TRANSMITTERS

Description

YOU ARE  PURCHASING ONE LOT OF THREE 40 METER HAM RADIO CRYSTALS IN THE FT-243 STYLE HOLDERS, 7040, 7110 AND 7118 KHZ. I HAVE REMOVED THE ORIGINAL OUT OF BAND ELEMENTS AND INSTALLED THE HC49/U TALL VERSIONS OF THE HC49 TYPE CRYSTALS (2ND PHOTO).
I SOMETIMES FIND THAT THE SMALLER HC49/S CRYSTALS WILL WIMP OUT IN VACUUM TUBE CIRCUITS, BUT THE LARGER HC49/U WORKS GREAT IN MY ONE TUBE TV SWEEP TUBE (50CD6) CW TRANSMITTER (PLEASE SEE THE 2ND PHOTO FOR THE HC49/S AND 49/U COMPARISON. THE 49U, WHICH I HAVE INSTALLED IN THE CRYSTALS IN THIS LISTING IS ROUGHLY 3X LARGER THAN THE SMALLER 49S VERSION.
I'VE USED THE 49U CRYSTALS IN ALL MY HOMEBREW VACUUM TUBE CW TRANSMITTERS WITH GREAT SUCCESS.
I HAVE SEVERAL OF THESE, SO THE PHOTOS ARE GENERIC. THE CRYSTALS YOU RECEIVE WILL BE IN THE FT-243 HOLDERS, SIMILAR TO THOSE IN THE PHOTO. ALL CRYSTALS ARE TESTED BEFORE SHIPPING AND GUARANTEED TO BE GOOD OSCILLATORS.
ALWAYS WILLING TO COMBINE AND DISCOUNT SHIPPING FOR MULTIPLE ITEMS. IF YOU PURCHASE MORE THAN ONE ITEM PLEASE REQUEST AN INVOICE TOTAL BEFORE PAYING.
SHIPPING TO THE UNITED STATES ONLY.
