Its seems like a bit of a juggling act, fiddling with where one parks the screen vdc and how negative g1 is held. If you want to stay in a/b1 and try and squeeze 100w out of a pair and not have the screens do a melt down. And thats before any feedback is applied. Or the burden gets transferred to the driver. Indeed they have a 25w plate diss. rating...my vote would be to use a quad of 6883B and halve the opt primary impedance. :-) JH
