 Alpha 86  
Sale pending
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 RK2FS 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.
$2200 . . . A great price!

 KENWOOD TL-922L HF AMPLIFIER VERY NICE  
I'm selling my legal limit Kenwood TL-922L HF linear amplifier. This unit is in great condition inside and out. I have taken pictures of the out side as well as the inside. Just let me know if you need me to send you the pictures. I always take care of my equipment and I have a very nice custom made dust cover as well. I have the amp wired for 220V but can be easily wired for 110v. Asking 1200. firm pick-up only. Cash payment upon pick-up.. Will not ship... I may work a deal if your interested in the MFJ-996 automatic 1500 watt antenna tuner which I purchased new a few years ago and maybe used it 5 or 6 times. Just lost interest. Thank you de Don WB4GMN Shelby, NC. 28150

 FS Collins 204F-1 3.5 KW Amplifier  
I am selling my Collins 204F-1 amplifier. This amplifier uses a pair of 4CX-1000 tubes. It will tune 2 to 30 MHz continuous. Collins reports the duty cycle as 24/7, at 2.5 KW. This amplifier is in very good condition. It was built for the military with heavy duty components, and vacuum relays.
Much better built than anything sold in today’s market. No displays, IC’s or proprietary software that becomes unobtainable. There is a lot of information on the internet on this amplifier. Pick up in Northwest Oklahoma. It is big and heavy. It is not weak and unfit!
Selling for 3500.00. Cash, ZELLE, USPS money order accepted once the money orders clear my bank the amp would be released. Mason, K5yhx. 214 293-4050. More pics on request.
