Maybe 5-10W max over ratings for FM service. However all of those style bricks are horrible on SSB and lose linearity at about a third of rated output. The problem is the diode bias that is used goes

It sure is Bill but there is no Golden Rule that says you must use a Q of 12. That is only a ham lore number. The size of the 850 coil and switch surface indicates that there is plenty of room to pla
