    Has run trouble free for years. Used as a spare last few years and does exactly what it says on the tin.   Also fitted additional fan for cooling PSU.Top quality components, Some replaced during improvements. Output power up to 1600W  (50W DRIVE 800W O/P ON FT8 all day).


    Would prefer buyer to collect and test in shack. Collection only or meet by arrangement within an hours drive of Lancashire. This is not an item I can post.

    £500.. a bargain for 1500w . Same model for sale 2nd hand via a retailer for £1100, fully working order, never had an issue with it. Run at 50% most of the time.
