2. Integrated Active Output - $199 This is a prototype of a design intended to provide very good sound at an affordable price. It uses a very different circuit from the standard Active Output stage and does not require output transformers. The unit is assembled and tested. The board includes both the amplifier and the power supply so a separate power supply is not needed. A second bare PC board is included so you may build a second unit sometime in the future. The sound of this amplifier is very good but not up to the quality provided by the standard Active Output stage. Photo and schematic on line at http://www.raleighaudio.com/iao.htm (one available)
