1pair Pass Aleph-3 Fully MOSFETs 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 Accuphase E350 Power Amplifier.
Tech highlights:
Fully Discrete .
DC servo.
120Wate 4Ω (±40VDC).
75Wate 8Ω (±40VDC).
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：3VPP
Gain: 22X
input resistance: 47K
Output Power:
120Wate 4Ω (±40VDC)
75Wate 8Ω (±40VDC)
PCB SIZE:
71x153x1.6mm 1oz Cu, HASL with lead
Tips:
please prepare external heatsink.
Adjust 2K-VR clockwise to the maximum resistance value before powering on.
After power-on, slowly adjust 2K-VR counterclockwise until 22mVDC can be measured between BC,DC,EJ,FJ.
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.
