Sugden A21SE Special Edition Remote Volume Pure Class ‘A’ Integrated Amplifier (Line) – 30 Watts

The A21SE Integrated Amplifier is a single ended solid-state pure class ‘A’ design.  The pre-amplifier has a cascode input stage, current feedback with the input and output being in phase.  Other design points include high input impedance, high voltage gain in the first stage with low distortion, wide bandwidth, low noise and very low output  impedance.  Left and right line stages have current shunt power supplies from a dedicated transformer winding.  The input signals are relay switched reducing signal paths to a minimum.
The A21SE is capable of producing music in its most natural and organic form.  Free from crossover distortion, power can be delivered smoothly without the high frequency ‘pain’ associated with so many transistor amplifiers.

Facilities:

Inputs – Five line level operated by relays.

Ouputs – Pre-out (variable), tape out (fixed), one pair of stereo multi-way binding posts and LTVS supply for A21SE Stage One Phono Amplifier.

Remote Control – Volume up/down.

Specifications:

Line Input sensitivity – 110mV for maximum output.

Power Output – 30 watts pure Class ‘A’ into 8 ohms both channels driven.  40 watts pure Class ‘A’ into 4 ohms both channels driven.

Frequency Response – 20Hz to 20kHz +/- 0.5dB.

Bandwidth – 12Hz to 141kHz +/- 3dB.

Signal to Noise – >84dB.

Packed Weight – 14 kgs.

Dimensions – 115mm x 430mm x 360mm (HWD).

Recommended Retail Price – AUD$4,295.00.
