If you have one of those smallish 3 to 4 inch open end wrenches that fit the nut exactly, torquing it by putting pressure on other end of wrench with pinky finger only, can tighten it permanently with no danger to any component.
Long term operation of VFO B without that nut tightened properly is a greater threat to physical integrity of components behind the panel. 73 & GL Guy On Wed, Jul 27, 2011 at 1:38 PM, W5UXH <chuck.broadw...@gmail.com> wrote: > Hi Don, > > I really should have removed the knob before posting, but just had the mind > set that the noise was on the other side of the panel (no excuse for > deciding that of course). > > As soon as I took the knob off, the nut fell on the floor!
