Jadis JP-200

FEATURE

1. Circuit design is with reference to the classical Jadis JP-200.

2. 12AX7 x 6 pcs for amplfication.
3. Independent power supplies for tube power and tube filaments.

4. Double blue layer PCB, dimension of 210mmx180mm, 2.5mm thickness and 2oz copper.

Optional:
1. Adjustable Tube Power Supply 250V-400V 12.6V(1.5A)x2 / 6.3V(1.5A)x2 for Tube Preamplifier
2. Power Transformer T120

Critial Note in Assembly:

1. Connecter J3B is B+ (400 VDC) - you could slightly change it to boost the sound performance. The marking is incorrect. The marking "AC" should be connected to "GND", whereas "GND" should be connected to "B+".

2. Connecter 12.6V J4A and J4B is filament voltage for tubes. (The marking should be "DC" instead of "AC")
