Hi folks...I don't want to hijack this thread...but for those of you guys really needing a gen 7020 tube...I will have several NOS tubes coming in the next few weeks.....for those of you that can't wait.phong has an aftermarket tube/crown set that are acceptable.However, the tubes/crowns have weak threads and are prone to wearing out prematurely.The base metal used is less than ideal.the tubes also braek in the cases if you try to torque them too tight....
