Aurorasound PADA - Hybrid EL34 power amplifier - showroom unit in very good condition

This 120V showroom demo unit comes with eight Telefunken EL34 replicas and a new and unused octet spare Telefunken EL34 replica tubes. The unit also comes with full warranty.

The PADA is the leader of an innovative generation of amplifiers of state-of-the-art Hybrid design and construction, taking advantage of both the benefits of vacuum tubes, as well as transistors. Powered by the Slovakian-made replicas of the Telefunken tubes, produced in the US factory, the PADA provides a maximum output of 43W per channel, and is compatible with speakers having an impedance of 4Ω-16Ω.

Tubes
EL34 is a renowned European tube that has superb linearity in the tube connection. PADA utilizes the EL34 triode’s parallel push-pull construction in order to provide 43W maximum power per channel. The EL34s provide a tight low end and smooth mids. Known for its unique output stage, the EL34 brings new life to amplified music while retaining the historic tone that Telefunken tubes have always been known for. The EL34 tubes used in the PADA are carefully handmade in Slovakia by old-world craftsmen of Telefunken Elektroakustik.
In addition to a rigorous testing procedure, all Telefunken tubes are cryogenically treated and are subjected to an extended burn-in period to insure superior stability. The tubes are re-measured again after burn-in and again before final packaging, in order to guarantee that only the best, lowest-noise tubes are offered.

The EL34 is currently in mass production and will also be sold from Aurorasound for use in the PADA. The output vacuum tubes can be replaced with vintage tubes without any adjustments, which allows the discerning listener to enjoy a different character in the music. The PADA is also compatible with the KT150.

Architecture and Components
The frontend stage uses discrete transistors in order to achieve the lowest possible noise and distortion. The input stage offers genuine XLR input support. The inter-stage driver transformer is made by FineMet. The core material directs the signal path to drive the tubes in the final stage. Two independent power regulators, one for the frontend stage and one for the final stage maintain consistence throughout the entire dynamic range - from fortissimo to pianissimo. Output transformers from Lundahl of Sweden, are constructed with vibration-free symmetrical windings, and overall non-negative feedback so that the circuit will never be affected by counter electromotive force from the speakers. The 8mm thick casings are enclosed and cannot be opened.

The high-frequency characteristics are a result of long-lasting polypropylene film capacitors, that provide excellent performance in stable frequency characteristics, as well as the silicon carbide diode power supply unit.

Construction
The PADA has a top panel made of solid 8mm thick aluminum, a wooden housing and brass isolator feet. The rear speaker terminals are made of pure copper, and are gold-plated. They are compatible with 16Ω field SP impedance from 4Ω.

Two included covers insure protection of PADA’s exposed, fragile elements - a bonnet cover over the tubes and a cover over the transformers. The entire rigid chassis is constructed with non-magnetic material.
