h I-1FL-2IOO LINEAR AMPLIFIERGENERALThe FL-2100 Linear Amplifier is designed to match the FT-101/277transceivers in appearance and drive requirements to run high power inputcovering the ham bands 80 through t0 meters.The FL-2100 uses a pair of 572B/T160 transmitting triodes in a classB grounded grid circuit configuration.The tubes are foroed-air cooled bytwo very quiet high speed internal fans.Automatio Level Control circuit controls the exciter gain to allow thehighest average power without distortion caused by peak clipping.Change-over circuit biases the tubes to cut-off,eliminating unwanted heat and diodenoise generation when receiving.An internal changeover relay feeds the antenna to the exciter for barefootoperation when the FL-2100 is turned off or is on standby condition.A built-in SWR bridge measures SWR on by barefoot and linear operations.The built-in solid state power supply requires no warm-up period and pro-vides exoellent voltage regulation.CAUTIONDO NOT TURN ON THE FL.2100 WITH THE TOP SHIELDCOVER REMOVED.THE HIGH VOLTAGE SAFETY LOCKSHORTS OUT THE HIGH VOLTAGE AND WILL DAMAGETHE POWER SUPPLY CIRCUIT.
