a friend and I had the same problem once with a qro rig and went with two tall insulated standoffs with a singls strand of RG8 shield. Smaller wire would fuse at lower currents. gfz pentalab

speaking of fuse clips. do any of you guys know where I can get some big clips for fixed vacuum caps like used in the BC610 padder cap. I need to add a padder to my antenna tuner for 160 meters. I

Last 8281 I bought brand new set me back about $1050, and I think I had to add a socket. And, the tube's pushing good and hard at 20k, while a trio of YC-156's is loafing at 30K. Remember, a YC-156 is
