[TenTec] Operating AM with the Centurion amplifier

[Mark DeBord]

I am using the Orion II and the Centurion amplifier. I enjoy operating AM on occasion with this set-up. I load the amp at full output (using CW), but then reduce my drive on the rig to only produce total carrier output of the amp to about 150 watts. 
Can I increase my rig's drive to produce more from the amp without a concern (like 250 watts or so)? How long should I limit my keydown times? Do I need to add additional cooling with an external fan sitting on top or something like that? Any suggestions is appreciated.
I found a DX-60B at this year's Ten-Tec hamfest and plan on playing with it driving the amp too.
 
Any suggestions is much appreciated.
