Tech highlights:

It is based on the core circuit of the Musical-Fidelity XA50  Power Amplifier.
 
Tech highlights:
 
Fully Discrete
 
100Wate 8Ω  (±45VDC)
200Wate 4Ω  (±45VDC)
 
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: 21X
 
input resistance:   220K
 
Output Power: 
 
100Wate 8Ω(±45VDC) AB
200Wate 4Ω(±45VDC) AB

 
Tips:

please prepare external heatsink.

Adjust 1K-VR counterclockwise to the maximum resistance value before powering on.

After power-on, slowly adjust 1K-VR clockwise until 12mVDC can be measured between C-D,C-E,F-H&F-J..




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.
