Tilt n Bands

Once when I was a little boy, I heard my uncle's equalizer which he built into his stereo. 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 payer made.

I asked my uncle for the diagram and he drew it with a pencil on a piece of paper. I quickly learned the scheme by heart and as an electronic engineer amateur, I repeatedly build the hi-fi amplifiers using the scheme. The EQ sounded implausible each time.

After many years

After many years I decided to make a studio device based on my uncle's scheme. 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.
