So does the Alpha 87A when one considers that the Pi-L network essentially 
performs a similar tuning function on the 3:1 VSWR circle in that the load Z 
is matched reasonably well to the tube output Z.

I'm not sure of the replacement cost, nor the time involved with respect to 
replacement of all the output transistors in the PW-1, but it's probably a 
lot easier in terms of time and money to throw out a pair of 3CX800s than it 
is for a similar transistor replacement -- especially on a contest weekend.
