Qualiton A35

The Audio Hungary Qualiton A35 is a push-pull Class AB amplifier, designed to serve analogue enthusiasts.

Those who need a combination of a high-performance vacuum tube power amplifier and a versatile preamplifier, along with sophisticated technical details, built into a single chassis.

In this way, perfect matching is achieved – both sonically and technically – between the main signal processing sections.

All internal circuits were designed from scratch, utilising in house selected components, premium film capacitors, ceramic composition resistors, motorised ALPS potentiometer, 2mm thick 2 Oz copper PCB,

Also in house manufactured power transformer is shielded noiseless oversized, toroidal transformer and the output transformers are also toroidal and are manufactured in house.

This attention to detail results in the creation a low noise and low distortion high performance vacuum tube integrated amplifier, which is hand made in Hungary at their factory.

The Qualiton A35 integrated amplifier features the latest version of their sophisticated Automatic Bias Control System for the four power tubes too.

A35 Audio Venue

This circuit continuously monitors the behaviour of each tube and regulates the bias voltages accordingly, ensuring the smallest possible output voltage noise while guaranteeing the highest degree of linearity of the output stage.

It also prevents the sensitive, high permeability transformer cores from saturating by precisely equalizing the quiescent currents of the power tubes.

Finally, the bias system has a built-in soft-start function too, which prevents the tubes from drawing excessive current during start-up and eliminates pops and noises during power-up.

The above means that no further adjustment is required once the electron tubes supplied with the unit have been installed, the circuit automatically takes care of everything.

The A35 is a 2 x 35 watts integrated amplifier and comes from the factory with the following tubes:

4 x 7581A

2 x 6922

2 x 12AX7 tubes

The Audio Hungary Qualiton A35 is also compatible with KT66, KT77, 6L6, 6P3S, 5881 tubes

Audio Hungary Qualiton

The history of their firm started in the late 1940s. Rafilm National Radio-and Film technical Company was established by that time. The profile was very wide. In 1951 Audio Voice-,and Film technical Co., which was specialised in voice technology left from it. Audio line contained sound film projecting -,and amplifying equipments ,which became dominant. The development turned into electro acoustics and audio technology. Its name changed into Electroacoustic Factory, using the abbreviation EAG since 1960. Under the pressure of the German firm AEG it changed its name into BEAG ( Budapest Electroacoustic Factory). The really successful history of the Co. started by that time. It produced complete studios, sound systems, teaching equipments. Manufacturing in Nyíregyháza has developed from 1970. One of the most successful movements was the building of the full sound-system of the Moscow Olympics in 1980. BEAG, the biggest electroacoustic factory of the eastern block, broke into smaller units in the privatisation period. The main line, which contained the producing of amplifiers, loudspeakers, and microphones was continued by UNIVOX Ltd. In 1990, the old-established Budapest Electroacustic Factory (better known as BEAG) which mainly produced PA systems, was disbanded. At this time, based on the Nyíregyháza plant of the company, Univox Kft was established. This new company continued to offer a considerable portion of the product range of BEAG, including amps for industrial use, outdoor and indoor speakers, intercom systems and microphones. This extraordinarily wide product range was available for our customers until the beginning of 2014. In 2014, Univox Kft was bought by Audio Hungary Kft which perpetuated the name UNIVOX as a brand name. The production range did not cease to exist but the number of products went significantly down. Due to the fusion of the two companies, the huge body of this acquired knowledge and production experience enabled to create and produce premium category audio products. Following the most possible recent electrical and mechanical engineering solutions, by the first quarter of 2015, our specialists, relying on their considerable hands-on expertise—and complemented by the young engineering team of Audio-Hungary Kft—came up with the very first amp of the company, designed under supervision of the new management: the UNIVOX APX 200 tube power amp. This is their way of paying tribute to the appliance APX 100 of the company BEAG which now has been rendered into a remarkable piece of home consumer electronics by them. According to this, the amp features 4 Ω and 8 Ω outputs for a favourable price in its category. As far as the quality of their products is concerned, they do not make any compromises. Appliances launched under the brand name UNIVOX consist of electric circuits made of selected high-quality components. They are placed in solid and carefully conceived metal frames. They are working on developing durable power amps and integrated amps, designed for the Hungarian and international market, as well as—in addition to vacuum tube amps—on designing hybrid constructions using semiconductors. The development and launching of speakers and cables, belonging to the series, is in progress too. They are spending a great deal of time and effort perfecting one of the most delicate points of vacuum tube amps, the output transformer. Their transformers are excusively made in their newly set up plant on up-to-date toroid and linear coil winding machines. Finally, they hope that their appliances, made to meet with high technical demands, will be to the liking of all whether it is a preamp or a power amp, a hybrid amp or a full tube amp. QUALITY POLICY The management of Audio-Hungary Kft, designing, developing and producing high fidelity electronic devices, is dedicated to fully implement the requirements set out in their quality policy. The management of the organisation as well as the staff co-operate in order to achieve their objectives. Their organisation is dedicated to the implementation of requirements and continuously wishes to improve the quality of its procedures by consistently applying the quality manamegent system. They wish to outperform their competitors by ensuring high quality and maintaining reliable and regulated business relations. Each and every worker of theirs is accountable for performing his or her own task in a manner which makes consumers thoroughly satisfied. In order to achieve this, they permanently develop our coworkers’ skills. Their quality policy goals are: - Continuous development of their quality management system - Continuous acquisition of new customers - Production of consistently high-quality products - Customer satisfaction In line with their quality policy, they set quality goals for the achievement of which appropriate specialists and tools as well as conditions necessary for a quality operation are made available by their management.
