INSTRUCTION MANUAT FL-21o,o.z. YAISUmus$tc0.,trD. c P.o.Box 1500 ÍOKYO,JAPAN YAESU FL-2 IOOZ LINEAR AMPLIFIER The FL-21002 is à high peribrmancelinear amplifier designedfor all Yaesu HF SSB transceivef. This amplifier uses two 5728/T160 transnitting triodes in a ClassAB, grounded-gridconfiguration. Operation on the 160 through l0 meter bands is provided. C Two quiet internal fans provide lorced air cooling lbr the final tubes. An intemal changeover circuit biases the tubes to cutoff duÍing receive operation, thereby eliminating unnecessaryheat and diode noise generation. A unique safety ièature incorporated in the design of the FL-21002 is a momentàry bias delay circuit, which protects the tank circuitry from damageby delaying the activation of the final tubes until the T/R relay is firmly seated. An internàl relay connects the antenna directly through to the exciter dudng standby operation, or wllen the amplifier is tumed off. A built-in SWR meter is also included, for monjtoringof the feedlineSWR duringeitller ampliÍieror exciteronly operation. The power supply lor the FL-21002 is built in. lt requiresno warÍnup time, and its healy-duty construction provides excellent regulation.

CIRCUITDESCRIPTION The FL-21002employstwo 5728/T160zerobias triodesin classAB, grounded-gidconfiguration. RF d ving power from the exciter is applied through antenna changeoverrelay RL, and an input matching network to the filaments. The broadbandinput pi networksrequircno tuning to presentthe correctimpedancematch to the tubes and 50 ohmsto the exciter. A sample of the exciter RF is taken from the filamentsthrough Cr! to ALC rectifier diodesDr (151007)andD, (10D10).Trimmercapacitor TCr then servesas a voltagedividerin conjunctionwith Cr,, for adjustingthe levelof ALC voltageprovided for the exciterat J3. BAND 160 80 FREQ (MrL) The grid bias is set by Ra. When antennarclays RL, and RL, are activated(to transmit), Cao6 dischalgesthrough R3oa. The values of these componentsare selectedso as to delay activation of bias relay RLor long enougl to ensurethat the RLr and RL, are fully closed-This protective featurc preventsa momentaryopen circuit ai the ampliÍieroutput which might otherwiseoccurdue to rclay tmvel time. while the amplifier is set to standby,switchSa is openand the tubesare biased to cut-off. The plates of the amplifier tubes are connected through an adjustablepi network of the RF OUT jack, and the output is sampledfor dircctional relativepowermeasurement by a bridgecircuit, for power rclative and SWRindicationson the meteÍ.
