FS: Yaesu FL2100B: I have for sale from a local estate a Yaesu FL2100B linear amp if you need to boost your signal some for the pileups or contests. It is in very nice condition physically.
I tested it and was getting 500 watts out according to the MFJ wattmeter but wasn't pushing it real hard with the exciter either. It does 80 to 10 meters, using a pair of 572B tubes, and is currently wired for 110 volts. It comes with a copy of the manual and a cord with a phono plug on it for the relay. If you are using a newer radio you will probably need a linear interface for this.
I am asking $550 for it. Shipping is possible but an in-person meetup in the Oklahoma or Texas are would be great. It weighs 41 pounds to give you an idea as to what shipping might run.
