Thanks to all that responded to my want for Vacuum caps and couplers. Since nobody actually came forth and offered to sell me a CSVF 500 or any couplers, I called MGS and ordered them both from good

According to the formula a coil 5" diameter, 10" long, and 35uH would have to have 26 turns. This would be a coil with &plusmn;1/4" spacing between the turns. Bob W6TR _______________________________
