OK, we had this discussion earlier. Sounds like someone damaged the slugs with a metal screwdriver. The slugs are symmetrical. There will be an adjustment slot on the other end. You should be able to back them out though the hole in the board underneath the coil. It may be easier if you remove the coils from the board. DO NOT use a metal screwdriver. Get some orange wood sticks from the beauty supplies section of your local variety store and carve the end to fit the slot. the stick will break before the slug does.
The slugs themselves should be largely intact. You can screw them back in from the top and adjust them as normal. It should go without saying to not use a metal tool.
This is a problem that can be fixed.

It appears that L211 & L212 have problems on the RF side of the board. I founds small chips of it looks like core material in them. I am unable to section 5-6.2 to even come close to what it should be. Don't have enough expertise to troubleshoot this circuit. I have a good 100mhz counter good to 1hz and a Tektronics 100mhz scope so that is taken care of. I am open to any and all suggestions. I sent an email to Roon WB4HFN to see if he is still working on them.
73? Bob
What are the values of L211 and L212?
