KPA500 Protection on 60 Meters

[Roy Morris-6]

With my KPA500 in OPERATE (asterisk) mode on the 60 meter band, I have
turned down the K3/100 POWER on all five channels to keep my power level
from exceeding the low pass filter level.  Hopefully, this will take care of
the matter if I forget to take the amp out of the circuit.  Roy  W4WFB

What low pass filter level?

If this amplifier is going to blow up while delivering specified power then we
better be issued new front panels without the 60 and 30 meter buttons.
