The Series 7 version "R" Power-amp

The power amp is designed with a comparable specification to the Polestar III, as it relates to the EA range of two and a half years ago (in fact it should be slightly better). Power output is expected to be 50-55 Watts RMS into 8 ohms. It is a hybrid design with valves taking care of the 1st stage amplification and very high quality SS Mosfets delivering the output. Expect regulated HT with a 300VA torroidal PSU.
