[Amps] Triode Amps

[Kim Elmore]

I'm glad my amp has only *one* of these: 
https://mfjenterprises.com/collections/ameritron/products/383-1200-z7-2
at $3499 a shot, except that mine uses the earlier -A7 version which is 
even more expensive and nearly impossible to find. Fortunately, years 
ago a friend found a good pull for me at a hamfest for $400, so I'm set.

The 3-500Z is an excellent tube, but 1500 W isn't reasonably available 
out of a pair, even at increased plate voltage.
