 Load
has small value about 10 to 20 Ω.
 Transistor should have small value of β about
20 to 50.
 Input voltage is high about few volts.
 It has high power output and low voltage
output.
 Collector current has high value.
 Transformer or tuned circuit is always used.
 Output impedance has low value.
