 Ameritron AL-84 HF Amplifier  
I'm putting this up for sale (SOLD AS-IS, NO RETURNS) It's not totally dead but it has some issues. I'm not sure if the tubes are bad or not, but the output power started going down, during a contest, and I shut it down. There is a hole in the top of the chassis to gain access to the tubes. I just put a piece of wood on top of it, to help with the cooling fan on the back. This amp does cover 10 Meters as well. I do have some extra tubes, and I will ship them separately, if you want the amp, as well as pull the tubes out, before shipment. $250 OBO, plus actual shipping costs. I'd just need a zip code. My guess is about 30 pounds, as the amp weighs about 24 pounds, and I'll pack this up good, and probably ship the amp UPS, and the tubes, USPS. Call if any questions, or if you want more pictures, 7A-9P, MST, 7 days a week, as I'm not always around a computer, Leave a voicemail if I miss you, and I will call you back. E-mail is okay as well. Thanks!!
