The band Coverage of the Heathkit SB-200 includes the 80, 40, 20, 15 and 10 meter bands. The input power is 1200 watts SSB and 1000 watts CW with 100 watts of drive power. This amplifier has a continuous duty cycle using SSB voice modulation. Using CW the duty cycle drops to 50% with key down not to exceed 5 minutes.
The third order distortion is -30db or better at 1000 watts PEP. The output Impedance is between 50 to 75 ohms unbalanced and is a variable pi-output circuit. The SWR should not exceed 2:1. The input Impedance is 52 ohm unbalanced with a broad band pretuned input circuit that requires no tuning.
The meter has numerous functions which include monitoring the Grid Current, Plate Current, Relative Power, SWR and voltage(1500 to 3000).
The tubes in the SB-200 are Two 572-B's in parallel. The power requirements to run this beast is 120 volts at 16 amps or 240 volts at 8 amps.
This amplifier is 14 7/8 inches wide by 6 5/8 inches high by 13 3/8 inches deep. The weight is just 35 pounds.
