An integrated amplifier with a large number of inputs, which is capable of delivering 33 watts with an impedance of 8 ohms and 40 watts if the impedance is 4 ohms.
The Sugden Masterclass ANV-50, the 50th anniversary model in the famous series, largely pays tribute to the company's first transistor amplifier, which hit the shelves 50 years ago.
J.E.Sugden flaunts the completely manual assembly of its devices (with one master assembling the device from and to the device) – and the Sugden A21SE amplifier is no exception. The output power is low, only 2 x 30 watts at 8 ohms or 2 x 48 watts at 4 ohms, but note that the amplifier operates in Class A. The frequency band is phenomenal – 6 Hz - 280 kHz.
