  Here's a couple of photos;
 
The first is the Ken-Rad 6A6 and below it an RCA 6N7.
 
 
 

 
 

 

 
Wow, avant-garde looking towers!

this may be a silly question
the 6a6 does not have the center guide pin,post, so orientation doesn't matter when installing into the adapter socket ?

Not silly at all.

Two adjacent pins of the 6A6 are wider than the others and these slot into two adjacent wider holes in the adapter. It's obvious once you have them in your hands. You have to push quite hard to slot in these pins but they are very secure. 
Have a look at the holes in the adapter in this picture and you can see the front two are wider.

i kind of thought there was something going on there, 
my 6sn7 adapter  will be coming in from jeremy over the weekend, next up will be the more "exotic" tube options
among the tubes i got from joespride, i have a sylvania 6sn7, the 7193 adapter and ken-rad tubes , so i have those to play with
for a while, then i'll try some of the others
 
 
thanks !

Yes it's better to take these tubes one step at a time as you are doing. It's much more informative and helped me to decide  which I prefer.

i agree
 
i just realized something, i have a sunrise, not an ember, and the 7193 adapter will cover the biasing pots

  i have the same problem with Starlight. I just remove the top plate when biasing that way I have space to reach the screws with the screwdriver.

i was wondering if that might work

  That dual 6J5 adapter is a one-man show

Mine plugs into the 6sn7 adapter.   Is there a 6j5 adapter that is direct into the ember (IE... no 6sn7 adapter)  and clears the top plate ?  The 1 linked above does not look like it would clear the top plate anyone know ?

uuuugh, I can use my 6sn7 adapter if I must

It will depend on which version of the 6j5 adapter you get, the 1 linked above appears to plug straight in with no 6sn7 adapter needed (clearance may or may not be an issue).  My 6j5 adapter is to 6sn7 and so I must use the 6sn7 adapter which means no clearance issues
