 Ameritron AL-82   
Selling my AL-82 amplifier. This is a late model amplifier and is very nice inside and out. I installed new Amperex tubes less than a year ago along with 10 cap conversion to handle the 3700VDC better than the factory 8 cap. Amplifier works perfect. Plenty of pictures available $1900. Will ship or you are more than welcome to come pick it up, check it out and operate it at my shack.

 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.
