Puresound A30

£895.00

The puresound A30 amplifier was developed to meet the demand for an affordable Class A amplifier that would be compatible with all types of loudspeakers. The A30 is a line level integrated design that allows for the selection of up to 3 different source components and control of the volume by a high quality ALPS Blue Velvet potentiometer.  Class A operation was chosen because it gives lower distortion and a more relaxing, natural sound.

The amplifier uses the very robust Electro Harmonix 6550 output valves in an Ultra Linear Push Pull configuration.  This arrangement gives a combination of power and clarity that is difficult to beat.  The amplifier uses an Auto Bias system, which means that replacement output valves should be fitted as matched pairs.  There will be no need to reset or monitor bias conditions.

Very high quality components are used throughout including selected carbon film resistors and SCR polypropylene capacitors.  The power supply makes use of twin valve rectifiers and choke smoothing.

The output can be configured for use with 4 or 8 ohm loudspeakers. The output stage can also be switched to triode-coupled configuration.  This further linearises the operation of the valves at the expense of some output power.  It may be preferable with higher sensitivity loudspeakers.

The A30 may also be used as a very high quality stereo power amplifier if the volume control is turned up fully. When partnered with appropriate ancillary equipment the A30 is capable of very satisfying performance. 

The amp is in excellent condition including original box so can be shipped.
