A single gain stage based on the CCDA topology, the CCDA Mono Noval PCb will find many uses, such as line-stage amplifiers, front-ends to single-ended power amplifiers, and even headphone amplifiers. The PCB is small, being only 3 inches by 5 inches big. The PCB holds one CCDA (Constant-Current-Draw Amplifier) gain stage and one RC B+ voltage filter and two output coupling capacitors.
PCB includes 20-page user guide.
