[R-390] R390 progress 6AK5/6AJ5

Dan,

Your talking about the 6AK5 vs the 6AJ5.
There are so many differences between the R390 and the R390/A.
As we look back on the history of the receivers we wonder what was driving
the design. We do speculate and have created a few dead horses along the way.

Sure is nice to hear you are making progress. 
Mostly you are doing what you want to do and enjoying it.
That what's supposed to happen.

Keep the solder flowing.
