Ok, I see what you mean... although we did just recently "inherit" the old 
tube beastie from WARV, as a backup. One of these days, I need to get that puppy 
up & running again.

I think there are many stations that still have their "Ol' Bessies" as 
backups. 

Onto another question:

Today's modern transmitters can be set at power levels between almost zero 
and full power. In one box, you have an "infinitely" variable power level that 
can be assigned to each of those presets with a few turns of a screwdriver. (Or 
a code punched into a computer-based interface.) For example, our Harris 
Gates 5 has six presets. With a simple contact closure, we can select any one of 
them. Each one has its own trimpot, so we can set them to any arbitrary power 
level we desire. I have verified acceptable operation all the way down to 50 
watts, although Harris only spec's it down to 500. (It's a 5K box.) It can be 
set lower, but the audio quality starts to suffer a little. It's also quite 
wasteful to run such a large unit at "flea" power like that. Better to buy an LPB 
box for levels below 50 watts.
