GI7B Six Meter Amplifier Project - Update 2

If is quite difficult to get small diameter of copper tubing. It needs to buy at least a roll of several meter of quantity. So I give up this kind of material. Looking around and thinking of using surplus short length of hard line cable, center conductor is 5mm diameter. Wound 4 turn, inner diameter 40mm.
Doorknob capacitor is 1000pf 15KV purchased from Mainland China.
