LOT OF 2 HAM RADIO CRYSTALS FOR THE OLD BOATANCHOR 80M CW TRANSMITTERS

Description

YOU ARE  PURCHASING ONE LOT OF TWO 80 METER HAM RADIO CRYSTALS IN THE FT-243 STYLE HOLDERS, 3535 AND 3550 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 ALSO HAVE OTHER FREQUENCIES IN LIEU OF THOSE LISTED, SUCH AS 3560, 3576 AND 3582 KHZ. JUST LET ME KNOW IF YOU WANT ANY OF THE LATTER FREQUENCIES INSTEAD.
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. IN MY TRANSMITTER, WHICH RUNS ABOUT 100 MA PLATE CURRENT, THEY WORK JUST AS GOOD AS THE FT-243 WITH A STANDARD CRYSTAL ELEMENT.
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.
SHIPPING TO THE UNITED STATES ONLY.
