1pair HOOD JLH2003 Single-End 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 JLH2003 Power Amplifier.
Tech highlights:
Fully Discrete .
Single-End Class A.
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 Transistors per channel for power output.
Maximum input voltage:3.8VPP
Gain: 11X
input resistance: 47K
Output Power: Class A 8Wate 8Ω
Recommend to use CRC filter after rectifier.
Tips:
please prepare external heatsink.
Adjust 100R-VR clockwise to the maximum resistance value before powering on.
After power-on, slowly adjust 100R-VR counterclockwise until 110mV can be measured between TP-a&C,TP-a&D,TP-b&E and TP-b&F.
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.
