Like all amplifiers from the Italian company MastersounD, the integrated Compact 300B amplifier operates in pure Class A. The Compact 300B uses audiophile lamps - two ECC802, two 6SN7 GT and two 300B, and all connections are made manually at our own factory. An original automatic offset adjustment scheme has been developed for the stable operation of all lamps.
