The Audio Hungary Qualiton A75 is a single chassis integrated amplifier from Hungary, it weighs in at 21kg.

Its four KT 120s provide 75-watts.

For those with a collection of tubes, your KT88s, KT150s, and KT170s are all compatible, though they all produce the same 75-watts, per Audio Hungary.

The input tubes consist of four 12AT7s and two 12AX7’s

The amplifier operates in class A/B with 4 and 8 Ohm speaker taps around back.

Beefy transformers are all made in house, as are all Audio Hungary amplifiers.

There are four inputs, three single ended and one balanced.

Input selection is accessible via the remote or a single tiny toggling input button on the front that is easy to locate because tiny LEDs shine a light on the buttons associated with the source.

The rectangular remote is simple and has only a few functions. With it you’ll be able to toggle through sources, volume up and down as well as mute what’s playing.

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.
