QRP CONVERSIONS 40 METER CW 4 PACK IN FT-243 HOLDERS

Description

YOU ARE PURCHASING ONE LOT OF 4 QRP CRYSTALS IN USED FT-243 HOLDERS. ONE EACH OF 7030, 7035, 7045 & 7050 KHZ FUNDAMENTAL FREQUENCIES. I HAVE USED THESE LITTLE CRYSTALS WITH GOOD SUCCESS IN LOW POWER QRP RIGS AND HAVE SOLD HUNDREDS OF THEM TO OTHER HAMS WHO HAVE HAD GOOD RESULTS.
HOWEVER, THEY ARE GOOD FOR LOW POWER ONLY. THESE ARE SMALL QRP CRYSTALS (SEE PHOTO), SO BE CAREFUL HOW MUCH CURRENT YOU DEMAND. I'VE NEVER DESTROYED ONE, BUT THEY CAN BE DAMAGED IF YOU PRESS THEM TOO HARD. I'VE HAD HAMS TELL ME THEY'VE USED THEM IN THE OLD HEATHKIT TUBE RIGS, BUT I'D ADVISE USING THEM FOR QRP ONLY. THESE CRYSTALS ARE DESIGNED FOR USE IN TRANSISTOR OR LOW POWER VACUUM TUBE CIRCUITS.
IF YOUR INTENDED USE IS FOR A 6V6, 6L6, 6DQ6 OR SIMILAR SINGLE TUBE TRANSMITTER, THESE LITTLE CRYSTALS WILL PROBABLY NOT HOLD UP. THEY ARE NOT DESIGNED TO HANDLE THAT MUCH POWER.
I HAVE SEVERAL SETS AVAILABLE, SO THESE ARE GENERIC PHOTOS. ALL CRYSTALS WILL BE IN THE FT-243 HOLDERS. THE CRYSTALS ARE NEW, BUT THE HOLDERS ARE FROM OLD USED STOCK. I SIMPLY POPPED OUT THE ORIGINAL CRYSTALS AND REPLACED THEM WITH THE CRYSTAL TYPE THAT YOU SEE IN THE SECOND PHOTO.
SHIPPING TO THE UNITED STATES ONLY.
