 Ameritron AL1500  
Ameritron AL1500 in splendid physical and working condition. Has a genuine Eimac tube, Peter Dahl transformer, factory wired for 240V and puts out full legal limit. I tested it with a dummy load using a Telepost LP-100A as meter. I purchased from the original owner who is now a silent key and just never got around to using it. I'm listing here hoping someone can pick it up in person as I dread shipping such a heavy, fragile item. $2800

 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. 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.
