[QUOTE="Tim McCulloch, post: 63801, member: 67"] Re: HF Diaphragm Question You may or may not have properly installed the diaphragm. It's been a long time since I've had to replace one, but in essence you finger-tighten the screws and then do a sine wave sweep. The instrumentation is to show the distortion or impedance change from a VC that rubs or is otherwise not centered in the gap. The screws are finger tight so you can gently move the assembly while observing the changes; tighten them down when you're sure everything is correct. [/QUOTE]
