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.
