[TowerTalk] KT34-A elements to insulators assembly question

Thu, 7 Sep 2000 03:40:47 -0500

Anytime you want a nut that won't come loose, get on with a nylon insert.
These are called "shake proof" or "Nylock"  and can be had at any large
hardware store for about a nickel a piece. You can use them alone or as a
jam nut over the top of the regular one, assuming there is enough thread
left over.Geo>K0FF

>I purchased a new KT34-A about a year and a half ago.  I now have a

>I have reached the point where I am mounting the element sections to the
