I have the Yaesu FL-2100B HF amplifier. It covers 10-80 meters and is in great working condition. Has full power output and comes with the manual and also the accessory connection cable and plug for a Yaesu FT-101 transceiver. It can be used with most other transceivers as well with the proper connection cable. Still has the plastic protective covering on the front panel. Sold as is but will be working as stated upon arrival. I will ship with the tubes installed unless buyer wants them removed. $55 shipping in the US.
