Well the mark vi+ arrived in very good time three days in transit . No damage was evident to the packaging and everything inside was present and in good order. After unpacking everything I noticed that one of the alloy rings at the base of the tubes was very loose, not a functional issue but a sign of poor quality control. Set up was a simple matter of fitting the tubes and cables no problem although the tubes were very tight. Hit the power and my first thought was those fans will have to go, the fan noise is far too high for this type of product ,they were clearly audible from the next room. Then silence, the fuse had blown so I checked all the connections replaced the fuse and tried again the valves began warming then as the right hand meter started to light pft the fuse blew again. After an email to David who advised the problem was probably a bad tube I spent some time in reflection. Since the amp was brand new I had not had time to collect any spare tubes and so could not test the bad tube diagnosis. A combination of disappointment and shock led to a decision to return the Mk vi+ and seek a refund, probably an over-reaction I admit. On receiving the Mk vi+ David confirmed the problem was a bad tube then without fuss or further comment issued a refund including my return shipping cost.
To conclude this chapter I cannot comment on the sound quality of the Mk vi+ as it never functioned, I can say the fans are a problem and were a large part of my decision to return the Mk vi+, I can also say that the customer service from Little Dot is outstanding and David will go beyond the letter of his already excellent warranty to ensure your satisfaction.
