JUNGSON JA-2/JA-50 PREAmplificateur et Amplificateur de Puissance HIFI Deluxe Version Mono Amplificateur CLASSE A 80W

JUNGSONJA-2/JA-50HIFIDeluxe Versionamplifiermono AMP mono amplifier

Circuit characteristics:

Circuit design features of JA-2 pre amplifier. Since the JA-2 pre amplifier is balanced amplifier circuit design, each channel must have a positive, negative two sets of DC power supply. The whole machine voltage amplification part adopts parallel voltage stabilized power supply. This stabilized voltage power supply in the structure than the general requirements of a series of higher, greater capacity.

JA-50 is a set of two pieces of a balanced single channel amplifier and JA-2 parallel put together very harmonious.

Characteristic:

1. The JUNGSON core of the original, a full symmetry without feedback loop, full balanced transmission technology.

2. It followed the JUNGSON flagship product of noble descent, the use of the same core technology and the flagship; the key components are almost the same. For example: 800VA Special square transformer, Advanced 9.6W uF filter capacitor,HIFI Coupling capacitance, A1295/C3264Sanken Tubex 4 for each channel,15031 15030 Drive tube.

3. Volume control using the world's top technology (The United StatesJeff Rowlalldamplifier potentiometer control technology). It is equipped with a rare wooden remote control.
