A28B Integrated Amplifier
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.
