About Rolls PA253

Enhance your audio experience with the Bellari PA253 42W Stereo Power Amplifier, a product meticulously crafted with an unwavering focus on superior sound quality. This high-performance amplifier is constructed in Salt Lake City, Utah, with every step of the process carried out by skilled American workers.

The robust chassis of the PA253 is crafted from high-quality steel sheets that are precisely cut, bent, and formed to create a sturdy and durable structure. The steel is then treated with a high-gloss red powder coating, adding a touch of elegance to its aesthetic appeal.

At our Salt Lake City factory, we silk-screen the chassis and assemble the Printed Circuit Boards (PCBs). The PCBs are flow soldered and then sent to post-flow assembly, where delicate components are carefully hand-soldered into place. Each PCB undergoes rigorous testing before being sent to mechanical assembly, where the PA253 is brought to completion and tested once again to ensure optimal performance.

The packaging for the Bellari PA253 is as locally sourced as the product itself. The boxes are produced in a facility just a few miles away, and even the outbound shipping boxes, biodegradable peanuts, and printing materials are all made in the US.

While some components like the power adapter, jacks, knob, and ICs are sourced from other countries, we take immense pride in keeping as much of the production process as possible within the US. This includes 100% of the product development and design, ensuring that every Bellari PA253 42W Stereo Power Amplifier you purchase is a testament to American craftsmanship and quality.
