" Hope it's not the magic DX foam that allows the S line to hear signals others
can't"


Gee.....

(snips)

>>stuffed foam in there to "dampen" the filter -- 

>>"insulation" value, keeping the filters a more constant temperature???

>>Any old foam material will do.  It merely held the filter in the socket -

>>when that foam deteriorates like that it greatly reduces
the sensitivity (insertion loss).

Shoot !!!  I was hoping it was the " Magic DX Foam".....
