Still looking for a 75pf - 100pf air variable for low power application, must mount with a single 3/8" nut and have at least 1" of 1/4" shaft past the threads for the nut. This will be c-1 in the output circuit of my 6ag7/2e26 cw rig The one I had was so old the ceramic crumbled! Thanks and 73 Ronnie Sent from Ronnie's IPhone
