Please see images for valve set. The puresound A30 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. THD+N: 0.1% 1W, 1KHz, 4 ohms.
Input connections: Three analog Rca. Dimensions: W470 mm x D430 mm x H128 mm.
