 “When I received the Audio Hungary Qualiton amp, I had no idea what it would sound like. I was more than pleasantly surprised by how great it is. But the real news is that this is a 100 watt per channel, well designed and built, pure tube signal path design with all the revered sonic qualities of a very high-end and typically very expensive power amp, yet can be had for the asking price of about $6,000 ... It’s a steal. Boom ! You’re welcome !"

the beauty and the beast


Class A-AB PP Bridgeable Stereo/Mono Power Amplifier


The P200 delivers fully 2 x 100 W in Stereo and 2 x 200 W in bridged Mono mode,  and is consequently able to dynamically operate very insensitive speakers. This is achieved by a pair of KT120 tubes per channel operating partially in Calls A (~12W) and predominantly in Class AB. The input and driver duties are handled via two 6N23P and two 12AX7LP tubes. A version of this amp can be ordered with KT90, KT150 or KT170 tubes.

The frequency response of the power amp is fully linear in the audio-frequency range, at nominal, i.e. 100 W output power, measured with sinusoidal waveform. The low frequency breakpoint of the frequency response is 18 Hz, the upper cutoff frequency is 60 kHz (-3 dB points). In the entire audio-frequency range, the total harmonic distortion is less than 1% and the signal-to-noise ratio of the amplifier is typically higher than 101 dB. While developing this product, the listed technical parameters were attained due to carefully designed circuit arrangements, a selected set of vacuum tubes and an accurately dimensioned and a manufactured output transformer.


The protection of the vacuum tube set is handled with special care. The lifespan of the tubes can be drastically reduced by uncontrolled transient surges of current at the moment of power-on. Similarly, suddenly switching high anode voltage on non-preheated vacuum tubes can have an adverse effect on the lifespan. In order to eliminate those effects, the appliance is equipped with a slow-start circuit and an anode voltage delay circuit.
