Interesting discussion .Ok I ran my carrier up to 400 watts the other night in the ghetto.Everyone said it sounded good.My 813s still arent showing any color even after a good old buzzard transmission.The pep is still the same ,the neighbors dont complain so I guess its ok.I realize that no one will notice a 25 watt power increase at that power level ,but it does make me feel like I am more strapping now.Thanks.
How may 813s do you have in your final, and in what mode are you running them? In class C, a single 813 is good for 2000 volts @ 200 mA, no problem.
I can't speak to linear service directly, only to the calculations for figuring power v/s dissipation.
CRANK UP THE WICK ! You have plenty more to go
