QUALITON A20i

 “What I can also tell you about the A20i is how well it lets you in on the textures and harmonics of music; how the sounds decay, how the music blooms, how it conveys a seamless continuity of the instruments in their space and the complexity of emotions of real music. This is an amp that focuses your senses on the music ...

... and makes you completely forget the equipment."

AUDIO HUNGARY QUALITON A20i   

Class A / PP Integrated Amplifier

 

Stereo, Class-A integrated amplifier with push-pull circuitry. The rated power output of the appliance is 20 W per channel. The power tube is the 5881 which is a ruggedized tube version from the infamous 6L6 tube family ... amongst having many qualities, this tube is also known as the "king of Jazz".

This family of tubes is very large, and substitutes include all 6L6 versions, the Russian 6P3S-SE, 7581A, and with simple socket adapters the 807, 5933WA 6BG6G, 7591A and at least 6 others !

The outputs at the rear panel can be connected to 8 Ω nominal impedance speakers. The design of the output transformers of the power amp enable to connect the amp with 4 Ω nominal impedance speakers as well. This entails a slight deviation from the parameters indicated in the technical data sheet.

At the front panel, the volume control potentiometer and the input selector rotary switch are connected to the same shaft. Indicators informing about the actual state of the amp are also located at the front panel as well. One can monitor whether the appliance is ready for operation (if so, the LED next to the volume control turns from red to white). LEDs also indicate the actual position of the input selector unit. The amp is made of solid, 1.5 mm thick, polished stainless steel sheet.
