"The idea of re-tubing an NCL-2000 with Svetlana tubes is quite intriguing.  
I would think it would be virtually certain that the 4CX400A would fit, 
since it is slightly smaller in diameter than the 8930, which is in turn 
slightly larger than the 4CX250.  While this might not make legal limit by 
the datasheets, it's probably a good match overall (plate dissipation, power 
supply, etc.) to the original 8122s.  They are, however, relatively 
inexpensive - RF Parts sells them for $140 each, and I suspect somebody like 
W4TH might beat that price."

================================================================

You are exactly right Dave.....I sell my Svetlana 4cx400a tubes for $180.00 
per PAIR.....that will save the guy $100 when compared to RF Parts cost. 
These tubes carry a full 1 year warranty as do all my ceramic tubes.....I 
dont carry the sockets, but they are easy to find as they are the same 
sockets as the 4cx250b uses....Max Gains Systems was selling a used pair of 
sockets with chimneys for less than $10 a pair.....if they still have them 
it would be just what he needs.
I would also suggest my Tetrode kit for the 4cx400a.
