Puresound A30-R Class A Integrated Amplifier

New Features (from original A30)

⦁ Twin power transformers for cooler operation and reduced noise floor

⦁ Output transformers have improved laminate material/windings for greater bandwidth

⦁ Remote controlled volume control and mute

⦁ Luxurious high gloss black finish

⦁ Updated styling

The Puresound A30-R amplifier was developed to meet the demand for an affordable Class A amplifier that would be compatible with all types of loudspeakers.  The A30-R 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 Puresound A30-R operates fully in Class A up to its rated output so it does not change character at any signal level. There is none of the distortion caused by output devices switching on and off and therefore no requirement for excessive feedback to correct for it. The 6550 valves supplied are the extremely robust Russian Electro-Harmonix variety and are quite content with dissipating the power required to maintain Class A operation up to 30 Watts. The valve rectifiers used keep the high voltage power supply clear of the noise that can be introduced by silicon rectifiers. A substantial choke is also incorporated to keep the power supply impedance low. The output transformers also give extremely wide bandwidth allowing very solid low frequency performance as well as exceptional reproduction of timbre. 

These design features combined with the use of high quality passive components, octal based input and driver triodes and an elegant but simple internal layout results in an amplifier which sets a new benchmark for performance, build quality and value.
