[R-390] Tubes

[Bob Camp]

Hi

There have been "big gulp" sales of R-390A tubes on eBay for quite a  
while now. I suspect that a number of us have more than a couple of  
spare tubes.

What do people need?

Is there enough interest for somebody to start doing tube sets again,  
or do one type at a time sales make sense?

I'm *not* trying to get in the tube business, just to see if there's  
a reasonable way to get around the shipping costs.
