You may be thinking of the 6293 which is a special version of the 6146 that was made for pulse modulator service. The 6293 can take up to 3000 volts on the plate. Also, the 6293 is an excellent repla

With what are you driving the SB-200? If a solid-state unit I would bet that the drive is actually falling off due to a mismatch in the input. The SB-200 is not famous for having a true 50 ohm input.
