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....
