Mart, Trever, Dave,

I just had an experience with the foil issue that made a believer in
"inner foil to out" or for coupling caps inner foil to grid of output tube.
The difference in my Mac 225 was less than subtle when I switched the direction of the coupling caps. I then did this for my series tweeter caps.
I think I heard a difference but I will not swear to it! In the case of the amp the sound was smoother and the hard edge I had went away. Go Figure! AC and just AF not RF, so whats the issue? I did not expect a difference so I can't say I was prepared to hear one! I've been told that Vacuum Tube Valley issue #11 has an article about this very issue. I need to get a copy to see what the story is. Now I'm really curious!
