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 into Class C. The
cure is a simple active bias circuit that holds the required 0.6V bias at
all drive levels.
I have the A1015 and B1016 ( the 3016 with a driver stage) schematics
plus full details on the bias ckt for a large SASE and 2 oz postage.
Unmodified bricks ( except Teletec) on SSB often lead to lynchings!
