INSTRUCTION MANUAL FL 21002Z YAESU MUSEN CO LTD TOKYO JAPAN O YAESU FL 2 100Z LINEAR AMPLIFIER X 4 EC EE e The FL 2100Z is a high performance linear amplifier designed for all Yaesu HF SSB transceivers This amplifier uses two 572B T160 transmitting triodes in a Class AB grounded gnd configuration Operation on the 160 through 10 meter bands is provided Two quiet internal fans provide forced air cooling for the final tubes An internal change over circuit biases the tubes to cutoff during receive operation thereby eliminating unnecessary heat and diode noise generation A unique safety feature incorporated in the design of the FL 2100Z is a momentary bias delay circuit which protects the tank circuitry from damage by delaying the activation of the final tubes until the T R relay is firmly seated An internal relay connects the antenna directly through to the exciter during standby operation or when the amplifier is tumed off A built in SWR meter is also included for monitoring of the feedline SWR during either amplifier or exciter only operation The power supply for the FL 2100Z is built in It requires no warmup time and its heavy duty construction provides excellent regulation We recommend that you read this manual in its entirety before commencing operation Operation of the FL 2100Z is extremely straightforward but improper adjustment of the controls and switches could cause reduced power outp
