CLASS A
POWER AMPLIFIER

Class-A power amplifier
Class A amplifier mechanical design

DESIGN

Our patented cooling system allows the Class A power amplifier to dissipate more heat in less space. With this technology it is possible to design an elegant product with a small form factor.

 

The amplifier chassis consists of a single solid aluminum block lowered with computer numerical control and thermally obtimized.
High technology for high-end products.

HIGHEST QUALITY

Performance

Better performance with 8 Ω and 16 Ω loads.

Input

Balanced input with high quality JFET transistors paired manually.

Sound

Reduced curly tension, low noise. Great stability, high dynamics.

SELECTED COMPONENTS

Power Supply

Linear power supply with low dispersion toroidal transformer up to 400 W and schottky diodes with low forward voltage drop and a very fast switching action.

CRC Filter

CRC type filter with Panasonic metal oxide resistors, Wima polyester capacitors and Mundorf MLytic series electrolytic capacitors with very low resistance and high capacity.

Protections

Speaker protection integrated circuit against direct current component at the output of the amplifier and delay circuit to avoid the 'thump' sound when the system is turned on.

CUSTOMIZE YOUR HANDMADE CLASS A POWER AMPLIFIER AS YOU PLEASE

The amplifier is still entirely handcrafted, welding the components manually on the printed circuit boards using tin and silver alloy. Once the PCB are finished, they are assembled in the anti-vibration monobloc aluminium chassis and their parameters are adjusted at intervals of time until reaching the maximum working temperature and, thus, achieve the most optimal result.

All connectors are Furutech. Optionally, the customer can choose the color of the chassis in black, red, blue, gold or silver.
