The sound was incredible. I still remember it to this day. Three potentiometers gave it a sound that I'd never heard before.

I couldn't stop listening to the sound that his compact player made. "I asked my uncle for the diagram and he drew it with a pencil on a piece of paper. I quickly learned the schematic by heart and as an electronic engineer amateur, I have repeatedly built the hi-fi amplifiers using the schematic.

The EQ sounded implausible each time. "After many years I decided to make a studio device based on my uncle's schematic. I improved the arrangement by adding a transformer balanced tube stage.

The Tilt turned out to be a cool addition too. This vintage circuit is very useful in any mastering application. I hope, you will feel the vibe of my uncle's old radio equalizer."
