LOT OF 2 HAM RADIO CRYSTALS FOR THE OLD BOATANCHOR 40M CW TRANSMITTERS

Description

YOU ARE  PURCHASING ONE LOT OF TWO 40 METER HAM RADIO CRYSTALS IN THE FT-243 STYLE HOLDERS, 7030 AND 7040 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 NOT HOLD UP IN HIGH POWER 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
(WILL SHIP INTERNATIONALLY IF PURCHASE IS MADE VIA THE eBAY INTERNATIONAL OPTION).
