1pair Musical-Fidelity –A2 Class A Power Amplifier Kit DIY
DIY KIT Project:
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .
To
complete this project, high level knowledge of electronics and rich
experience in terms of soldering and testing are required.
Due to
time zone and language communication restrictions, we can only provide
limited technical support, and you need to solve problems by yourself.
Tech highlights:
It is based on the core circuit of the Musical-Fidelity A2 Power Amplifier.
Tech highlights:
Fully Discrete
Max:30W 8Ω Class A (±33VDC)
Monarual design
single-point grounding, ground resistance is close to the 0.02 ohm, low noise design
PCB is small and flexible, very friendly for all kinds of chassis installation.
More cost-effective sound modification potential.
Total 4 Power MOSFETs per channel for power output
Maximum input voltage:3.8VPP
Gain: 13X
input resistance: 100K
Output Power: Class A 20Wate 8Ω(±24VDC)
Recommend to use CRC filter after rectifier.
Tips:
please prepare external heatsink.
Adjust 1K-VR clockwise to the maximum resistance value before powering on.
After power-on, slowly adjust 1K-VR counterclockwise until 0.47V can be measured between A-B,A-C,E-F&E-H..
Produkt-Konfiguration:
Fertige Platine: Basierend auf der gut getesteten Platine der Standardversion des Bausatzes haben wir die Spannung aller wichtigen Punkte überprüft und den Signalgenerator und das Oszilloskop für die doppelte Überprüfung der analogen Wellenform verwendet. Wir werden diese Platine nicht für Hörtests verwenden.
Bitte halten Sie die Spannung der Testpunkte nahe genug daran, +-20% ist auch erlaubt.
