I have to REMEMBER to keep the RF output to 65 Watts or less when using the AMP. Admittedly, I have put 100 Watts into the AMP a time or two, since the ALC is not hooked up, but it was only for a very short time, and the AMP still works just fine. I just want to prevent future instances of over driving the AMP.
I never use a ALC connection with a amp and always limit my drive power. I normally drive my amp with 50 to 55 watts and run the same power barefoot. When I need more power, I turn on amp. In your case the difference between 65 watts and 100 is less than 2 db so basically nothing is really gained by cranking it up to 100 watts barefoot.
