FS: Yaesu FL-7000 HF amplifier: I have for sale a nice working condition Yaesu FL-7000 amplifier
Amp puts out rated power on all bands. Physically I would say its a 8 out of 10. Wired for 115v service. Tested good. Not too sure about the tuner because it was alway bypassed due to the fact that most of these amps fail due to the ATU going bad. Price is $1100 OBO.
