[R-390] RF Module Adjustable Slug Seperated from Adjusting Screw

[Cecil Acuff]

Yes on reinserting and soldering and no on the dimension.(not usually, see 
below)  You will have to realign that stage for top performance.  It may 
have been loose and not aligned optimally anyway...

Do make sure it's not substantially shorter than the others on the same 
rack...I guess it is possible that the spring supporting the slug might have 
had the end broken off in which case you may have to find a way to make up 
for the lost distance as it may be out of adjustment range.

Be aware that the slugs in the R-390\URR and the R-390A\URR are not 
interchangeable nor are they within different positions of the R-390\URR RF 
deck.  Should be the same within the same color coded group though.
