Alpha 86: Great amp, qsk, pin diode switching, HEALTHY Eimac 3cx800’s, excellent condition. I hate to see it go but am remoting my station and need to go solid state with my Flex system and am replacing the 86 with a solid state amp. The 86 has been with me for 8 years. If you recall, when Alpha first advertised this model amp at Dayton, they put a brick on the key at 1500 out for the entire Hamvention duration. The picture here shows it at 1500 out with 35 Ma of grid current driving it with 42 watts from my Icom. The amp is in Fort Wayne, Indiana. I can deliver/meet so as not to try to ship it.
