The Sugden A28 integrated amplifier was produced from 1981 until 1995. It had four upgrades and the final version was the A28B, with 40 Watts per channel and the first 6 watts were class A. The pre-amplifier section was the same as the A21a and had the option of a phono stage. It was a popular product and has been very reliable over the years, we only see a small number returned for service.
