オーディオ・音響・アナログレコードのAurorasound（オーロラサウンド）

EL34 (6CA7）renowned European tube has superb linearity at Triode connection, PADA adopts this triode and parallel push-pull constriction to have 43W max power per channel. Frontend stage is organized by NEC and Toshiba vintage discrete transistors in order to secure very low noise and low distortion with simple circuit. Interstagetransformer made of FineMetcore material arranges signal path from frontend to drive the final stage power tubes. Output transformers are Sweden madeLundahlthat are no noise leakage dual coil structure, no casing, no dipping open style. Non over-all negative feedback circuit can get rid of counter electromotive force from speakers. Independenttwo powersupply systemfor frontend and final are keeping stabilityin any dynamic range from pianissimo to fortissimo. PADA is new generation hybrid power amplifier that brings out good combination of transistors performance and massive tube sound. Use Telefunken brand EL34 reproduced in Slovakia. Bonnet cover is bundled..
