Curious  question -- I recently wondered why it is that the 3-1000Z  
was never  that popular a tube in amateur circles, but the 3-500Z was.  
Why did  many amateur designs use two 3-500Zs instead of one 3-1000Z.  
Seems  like it would simplify things. One bottle and you could to the  
legal  limit with a simple grounded-grid circuit.

The market made some  determination, as 3-500Zs are still being made,  
and 3-1000Zs are  unobtainium....



Not positive to the answer to this but I think it has to do with the  
physical size of the tube.  Could you imagine the size of an Sb-220 if it  used a 
3-1000?  Hunter used one in their amp and it was not a very popular  amp.  There 
may be other reasons, but -physical size comes to my mind right  away.
