most tips and hints have already been covered, and these ideas only help prevent the slug turning what you need is to stop it falling, but most have not hit on the reason why it has happened The reason we inserted the rubber strip was to prevent the tuning slug from turning due to viabration, the threads are what stops the slug from falling to the bottom so lets take the ideas and use them wax as one person stated help to make the slug adhere ( sticky ) to the cavity wall threads one stated thread seal tape, my favourite is the threadseal tape but not wrapped around the slug, ( Fingers are to fat and podgy ) more cut to length and folded to make a simulated rubber band and insert into can, insert slug and tune i used to use at home when all else failed a thinly sliced piece of pla Marcus On Sun, May 30, 2010 at 4:37 AM, Doug Hutchison <[email protected]>wrote: > > > Hello, > > Got situation where the 'elastic' or whatever inside RX IF transformer > has disintegrated through age allowing ferrite core to drop to bottom > thus negating adjustment. > > What successful fixes have been found for such a problem which will > continue to allow adjustment yet not jam the core? > > Doug - GM7SVK > > >
