i need some 7.00 to 7.06 and 3.50 to 3.60 KHz crystals. i need them to be in the big holders. i am looking for some Bliley BC-3 or HF2 types. These are round (1.4 inch in diameter) with 0.75 inch pin spacing. i could even use an empty holder and i can put my own rock inside. They are for my Paraset Spy Radio... Paul w0rw at aol.com
