Those brass adapters reminded me of a question i wanted to ask . Didnt somebody on this thread experience at one point interference with these adapters  because they were made of metal.

Yep - won't work in my silver WA5 as it is a metal to metal contact.
 
They work great in my Wa6 as they are on top of my 6DE7->6SN7 adapters. That prevents the metal to metal contact.
 
Apart from the metal to metal issue, I found these to be good adapters to use. The caps have a nice tight grip that holds on quite well to the top of the 6F8G/6C8G tube.
 
EDIT - my version is the 6SN7->6F8G/6C8G variety. Similar brass construction.

I have - from a thread by Seamasters- suggestion.  They are nice "thinner" sounding then the 6sn7 I think a little but I like the sound.  The ecc804 is good too.  Gibosi wrote a post with several tubes that are compatible:
 
  Actually, there are a number of medium-mu triodes you can roll in addition to the 6CG7 and ECC804.
 
ECC88/6DJ8 and premium versions: E88CC/6922 and E188CC/7308. (These require the same pin adapter as 6CG7 and ECC804).
 
E80CC/6085 and 13D3 (These require a 12AU7 pin-adapter)
 
And each of the following require different pin-adapters
 
E182CC/7119 and 5687
ECC40
6463
2C51

These are the adapters I was looking at with the plastic base with a porcelain insert & a pair of tung sol's..
