Bella EXtreme 60 
6C33 Mono Bloc Amplifiers

 

The Bella EXtreme 60 mono bloc amplifiers are a unique design that utilizes the 6C33 output tube. Originally used in the Russian Migs fighter planes, the 6C33 has since been incorporated into tube audio amplifiers and is now found in some of the most highly regarded designs. The Bella EXtreme 60 mono blocs uses a pair of these tubes operating in push-pull for a dynamic 60 watts per side of Triode power. Cathode follower output.

As can be seen in our construction details, only the finest passive audio components are used throughout. Like all of our Bella EXtreme products, the EXtreme 60 mono blocs carry on the tradition of superior quality and workmanship and built to a performance level unsurpassed by other products anywhere near it's price point..
