I am deeply saddened by this news and my heart and condolences go out to all his family and friends who have known him over the years.
I knew Glenn from his very earliest days when he used to pop into a small business called Warstones Hifi run by a great character called Don Swain. This was in the early 1980s and I visited the shop which I think was based over a pet shop on the Warstones road in Wolverhampton. Glenn would drop in with his amplifiers and any of us who were lucky enough to be around would hear them hooked up to whatever system Don had in his demonstration room at the time. Some of you may know how Glenn started back then as he was part of a small group of audio enthusiasts who were investigating all sorts of valve amps to identify which designs were the best sounding. Out of this came Glenn's first designs.
The very first amplifiers I heard at Warstones were Glenn's OTL all valve mono blocks. What an introduction. The size and weight of these beasts was huge as would have been the heat and electricity bills! They sounded sublime. As I was at the shop so often I would bump into Glenn who would more often than not be in one of the back rooms looking at other equipment. Here I first got to know this great man who was both very quiet but very polite and forthcoming with his knowledge and suggestions.
I then went on to purchase his first Croft Micro which was probably the smallest and most basic amplifier he ever built but it sounded fantastic. I think it was about £125. After this the rest is a very long history of ever more sophisticated designs most of which I heard at some time or other including his very rare Cypher mono blocks. I purchased many amplifiers built by Glenn over the years and indeed today I use his 25R and Series 7 power amp.
I kept in touch with Glenn over the last 30-40 years usually via email and would often seek his advice which he would always give graciously. His amplifiers have been the basis of my HiFI journey all these years and I feel very lucky to have known him and owned many of his amazing designs and those that remain with me will be cherished for ever, a great testimony to this unique and wonderful audio engineer.
RIP Glenn
