DIY QRP PARTS FOR THE OLD BOATANCHOR TUBE TRANSMITTERS (HC49/U CRYSTALS)

Description: YOU ARE PURCHASING ONE LOT OF 2 CRYSTALS, 3576 AND 7110 KHZ, ALONG WITH 2 OCTAL BASES, AND 2 CAP COVERS, AS SHOWN. THESE ARE THE LARGER, HIGHER POWER VERSION OF THE HC49/S CRYSTAL TYPES. THIS WILL BE A DIY PROJECT. I USE OCTAL TUBE SOCKETS A LOT, AS SOCKETS FOR THE FT-241 AND 243 STYLE CRYSTALS. IF YOU'D LIKE TO DO THE SAME, USING YOUR OCTAL TUBE SOCKET, ALONG WITH THE TUBE BASES, AS A COMBO, THIS WILL WORK GREAT. YOU'LL RECEIVE ALL PARTS, AS SHOWN, BUT WILL NEED TO SUPPLY YOUR OWN TUBE SOCKET. I'VE USED THESE 49/U TALL CRYSTALS IN MY LITTLE 15 WATT SINGLE TUBE 50CD6 SWEEP TUBE HOMEBREW TRANSMITTER. IT RUNS ABOUT 85 TO 100 MA PLATE CURRENT AND THESE CRYSTALS WORK FINE, NO ISSUES. OVER MANY YEARS, I'VE SOLD PROBABLY 600 CRYSTAL PACKS, USING THE HC49/U CRYSTALS, AND TO DATE HAVE ONLY EVER HAD TWO COMPLAINTS. IN MOST ALL CASES, THESE QRP CRYSTALS WILL WORK IN THE OLD BOATANCHOR TUBE TRANSMITTERS. THE FREQUENCIES, AS MARKED, ARE APPROXIMATE AND MAY VARY PLUS OR MINUS 1 KHZ, DEPENDING ON CIRCUIT LOADING. SO THIS IS DIY. YOU WILL RECEIVE 2 CRYSTALS, 2 OCTAL TUBE BASES AND 2 OF THE CIRCLE CAPS. THE CRYSTALS SOLDER IN EASILY. JUST LAY THE CRYSTAL OVER A BIT, INSERT THE LEADS IN THE BASE PINS, AND SOLDER FROM THE TOP SIDE, OR ADD SOME LENGTH TO THE CRYSTAL LEADS, WITH SOME BUSS WIRE, AND SOLDER FROM THE BOTTOM END OF THE PINS. EITHER METHOD WORKS. ONCE SOLDERED IN, SIMPLY POSITION THE CAP ON THE BASE, AS YOU'D LIKE IT, THEN SECURE IT IN PLACE WITH A DROP OR TWO OF SUPER GLUE.
