[AMRadio] Sorta OT but just wondering about RF termination resistors.

My favorite dummy load is located inside the AN/URT-3 transmitter (4-400
modulated by 4-250's).
The xmtr operates at 100w out in autotune mode into an internal dummy load
consisting of 75 ea. 150 ohm 2 watt resistors.
I was quite surprised to find this batch of 2w resistors tucked away in the
RF amp drawer.
