[Amps] Pulser

The theory behind pulsing when tuning is to tune the radio (remember 
plate and
tune controls) without over dissipating the finals (sweep tubes and even 
the almighty
6146 included).
Works just as well for tube amplifiers. You just send a series of dits 
using the key and
peak the output. In my opinion then use a 'scope to check linearity of 
your amplifier.
But I'm old and no one seems to use 'scopes anymore.
But back to square one, you don't need another box in the shack, just 
use your keyer.
