 SPE Expert 1.3-FA Solid State Amplifier  
At 86 years old I have decided to sell some of my equipment, so I am selling my amplifiers and some radios. I have cables from KC5PCB for the Icom 7610, 7600, 7300 and 7100. These cost me $90.00 each but they are included.
I really hate to part with this amp as it is fantastic with so many different ways to connect to your radio or in that case radios.
When I bought this amp, I read the reviews from several different sources but the one from Mark Wilson K1RO at ARRL sold me on it.

I can't begin to tell you all the features and ways you can operate or connect to your computer.
It has four (4) antenna connections and will operate SO2R if you are a contester. I will list some of the sites you might want to visit to read more about this little fellow.
I comes with the original carrying case and I have padded boxes and, it will be doubled boxed and insured.
I am asking $2795.00

 ACOM 1000 HF + 6 Meter Linear Amplifier
I have an ACOM 1000 HF + 6 Meter Linear Amplifier for sale. It is the older brown model, but it is just back from a tune-up and is working well. It comes with a brand new tube. It also has an added fan to prevent over-heating, so should last for a long time to come. Cosmetically, it is in excellent shape with barely a scratch on it. Non-smoking, no animal household. I have replaced it with a digital amp that I can use remotely, so I have no use for this amp - my loss is your gain. Looking for some more power on HF/6? This is your answer. Looking for $1800 shipped. Work the world!
