[Boatanchors] AF-67/68 tube shields

[Lawrence Godek]

I have a bunch of the IIRC black tube shields.  I'd like to replace the 
silver colored ones in some of my equipment with the black IIRC ones.  I 
understand that those are the better ones to use if you have them.  
Anyone see any problems with doing this? Only thing i see is that the 
bottom of the black shields is totally different than what the older 
silver types are IIRC. Since they are not n front of me at this time i'm 
guessing that is the situation.  Never try and remember something that 
may or may not be as you get older.  In other words don't trust you 
memory, there i did it again.
