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.
